So yesterday I broke down and bought a webcam off eBay. I've decided to make a tutorial of what I can do, maybe it will help others out. I'll be posting here and on twitter, so check for it in a week.
Okay, and as far as illustrations, I swear things just snowball with me. Ultron went from a simple sketch, and now I have redrawn it as a vector and now I'm coloring it... Crazy. Here's a side by side:
To the left is the original illustration, colored in Sketchbook Pro on iPad, and the right is the vector illustration thus far. Only flats here, but I'm already 30% done shading Ultron. I'll probably be done tonight and share once again.
