Oh, I just love these! But with this one, I just can't but feel that the pencil sketch was definitely superior. It had more style and those loose lines actually look better. If I was your inkist/finisher on a professional workflow, I would be able to take that basic concept art and retouch your small errors to make it look better than the pixelart you currently have.\ Don't forget that you can make your lines wider than one pixel and also practice the "lost line" technique! (Lost and found edges) http://www.btinternet.com/~leoarte/edges.html It means sometimes the line tapers, or ends suddenly and sometimes it's not there at all and then suddenly picks up again . If you study a lot of really fine vector work, sumi-e or classic comics, you'll know what I mean. The thing about pixel art is that you have to be really careful not to lose the detail and style you had in your original draft. The roundness of the pixels, not pillow shading everything, etc. I used to do pixel art way back before Windows 64 bit MS Paint became crap. So what's the latest app for pixel stuff? (Please don't say GraphicsGale, it makes me want to stab my eye out when I'm already comfortable with Flash and I can just turn off anti-aliasing and work with a limited palette/PNG dithering for a retro look.) TL;DR what program do you use, and single-width pixel lines don't look as good as they could.
