I used Autodesk sketchbook mobile on the ipod touch, but for computer work, try and get hold of one of the following:
Paint Tool SAI
Adobe Photoshop CS2 up
I designed this guide so if someone wanted to colour in an eye they scanned they could. For a computer drawn eye with a transparent layer, always keep the line-art layer on top and use normal layers only to colour underneath!
Line-art for practice available here! [link]
For computer work, I usually work on Adobe Photoshop CS4. I'm going to thank you here for positive comments instead of typing in replies, because whenever I do i always clutter the comments with "You're welcome
" lol :L
Hope this tutorial helps you all!
