Thank you all for the feed back! I never really thought about that. I've never been one to do anything traditionally. XD I've never used MS Paint for pixels, so from the beginning, I've done things diferently than most people. But yeah, I'll practice with that. =3 I'm really bad with shading, it's my weak spot. So... should I dither for shading? I've only been pixeling* for a few months, and not very consistently. I use Photoshop CS5 for my pixel art, and I've been guilty of the blur tool many a time. XD
*Or I suppose I'm more of an index painting, or whatever you call it, artist? I'm by no means good at it, and I'm just starting out. I'm not very familiar with a most techniques.
As for the cat linearts, I haven't done much with them. The first one hasn't even been colored in. (It's transparent, just the lines)
Actually, I'm wrong on that. I've made adoptables with the second kitty lineart on chickensmoothie.com. =3
