idk if you are going to 'upscale' that small sprite but take care with the ribs texture. the small original one isn't really appealing to the eye, it's a bunch of banding. I suggest either lowering the number of the ribs so you can detail them better.
Look better?
Much, but the sternum gets thinner at the end i believe
its shaped kinda like a tie acutally
Tried to make it more tie like and some more wips
Final time i'm doing the girl with the pink hair I swear(i think this is the size I want it to be)
also changed the nut cracker sprite
I'm rescaling to help readablity. I'll also make the captain falcon a sprite.
Slow progress I can't think of what to do with the hair
Worked a little on the spikes for skull knight too.
I'm not fond of her nose, it kind of looks like it's at the wrong angle. Shouldn't the lighting run along the bridge due to the elevation?
Got a couple of qualms about the arm on the right. I think the shading is a bit excessive around the elbow area, there's something off about it.
The right line of her forearm also seems to have a little too much AA, makes it seem a little banded. I think the upper line of her panties also looks a little jittery due to the sel-out. Certainly not as smooth as, say, her face.
Tbh though, I'm mostly grasping here and thought it unfortunate your topic wasn't getting attention. I really like your work!
Her lower legs are too long compared to her upper legs, they should be about the same length (same case with arms, but you seem to have those down)
I tried shortening her legs and finishing her head, I realized it has a lot of jaggies but I'm still working on it.
