I've been experimenting with Draw Things, and seeing what results I can achieve with the thing.
Warning : Lots of (alarmingly similar) pictures inside!

Basic Samplers

Simplifying, the Sampler is the thing that reads what the current step has drawn, and informs the engine how to redraw things for the next step. If something "looks" like what you've asked for, it'll sway the engine towards making that bit look "more" like what you've asked for.
DrawThings comes with a bunch of Samplers, so we'll go through some of the basic ones to see what looks best.

And right from the get-go, the top-most sampler "UniPC" didn't seem to work in the slightest, leaving me with absolutely zip after 2 minutes of waiting.
Woot!


DPM++ 2M Karras
This one "worked", but there's weird wibbly lines all over the place, which have been amplified by the upscaler. It looks like it wants another 5 or so steps before it'll get up to a decent quality.


DPM SDE Karras
This one didn't work!.. Good grief!


PLMS
This didn't work. It's a lovely pile of tablets!


DDIM
This one ended up the same as PLMS, but more detailed. No good, except for better quality tablets.


LCM
This isn't a Bluescreen. Or maybe it is..?


TCD
This may also not be a Bluescreen!!


Euler Ancestral
Definitely the best so far.


Euler A AYS
And we have a winner!!!
There's not a lot of difference between Euler A and Euler A AYS, but it's enough to tip me over the edge, and declare this the overall winner of the Samplers.
Good job, Euler A AYS!

Note : There's also Euler A Substep, which is almost identical to Euler A, and Euler A Trailing which is almost identical to Euler A AYS.

We'll lock in Euler A AYS from here on.

Upscaler

DrawThings comes with a number of different Upscalers, which I've set to 400%.
Each one has its own advantages and disadvantages, some working best on one image type, and .. others on others!


Real-ESRGAN X4


Real-ESRGAN X4 Anime


Universal Upscaler v2 Sharp


Remacri


4x UltraSharp

Take your pick, really. I'll probably stick to Real-ESRGAN X4 Anime. It seems a teensy bit more contrasty to me, and a few things are a little more readable as a result.

Steps

The way these diffusion models work is they start with blurry dusty goop, then the Sampler tries to figure out what the blobs are, then it redraws with a few of the blobs more recognisable, and on and on until it's done.
It's really quite remarkable that it works, if I'm honest!!!

The more steps, the longer it'll take to render, because the more times it's iteraing as it draws.

Let's try numerous Step settings. (times are estimated!)


3 Steps - 2m:00s
The two Greenies have weird blue rims around their eyes, the noticeboard at the back has a black panel, and left Greenie's on a chair!


5 Steps - 3m:18s
Goldilocks!
Also, nice that Eric Cartman gets his picture on the wall.


7 Steps - 4m:30s
Big Chin Greenie!!
Right Greenie is fiddling with an alarmingly low microphone.


9 Steps - 5m:33s
The Greenie's upgraded to a flat screen TV! Left Greenie's chin has reduced a bit, but Right Greenie's arm has grown to bizarre proportions.


11 Steps - 6m:41s
Right Greenie's now sitting on the floor, Left Greenie is worried about the ceiling, and there's a nice amount of shadow/depth being added.

Honestly, out of those, I prefer 5 steps. It's a nice average amount of time, and the result looks great.
Of course, results will vary when I ask it to draw different things, but that's always been the way that these AI art generators work.

So. let's lock in 5 steps..

LoRA Weight

This is how strongly your LoRA influences generation, so the less like Greenie the Greenie will look.


22%
Well, at least he has a blue shirt...!
He doesn't have his long nose, he isn't balding, and doesn't have a red tie. Terrible!
Also, this is a wildly different room.


44%
We're starting to get a little more Greenie-like. He at least has a tie on, this time.


66%
He's still only one Greenie, but a few of our recognisable elements are showing through, like the noticeboard at the back of the room.


77%
Well, I guess that's Left Greenie starting to show up. The room is also much more familiar.


88% (This is the one we've been using as default)
Goldilocks!


99%
By this point we're going too far into the rules of the LoRA, so it's starting to trip over itself.
Left Greenie has two noses, and Right Greenie has been minimised!!


110%
Things actually look ok at this point. I was expecting much worse!
Note that Left Greenie is now more his cartoonish self, even though previously he's been Claymation styled, and that Right Greenie has vanished.


250% (for lols)
We're seeing a lot of that wibbly-line corruption that we saw right at the start with the 2M Karras Sampler. Cool for bizarro-world, but I think I'll stick to 88%!

And... That's about it, as far as the standard settings go.
There's other tweaks available lik a Sharpness filter, a Mask Blur, and things like that, but I've not really noticed all that much of an improvement from those.

So, um, yeah.
That's DrawThings for you.
Plenty of fun, as long as you watch your system's temperature!!
