Its a shame you didn't do it on white, plain paper so you can add color and all that. Looks way too good to be done on lined paper.
They serve as nothing more than penciled thumbnails (drafts of the art to come). Eventually I'll have a colored version done on a plain white index card, then another slightly more larger sheet of paper. I'll keep going until I'm satisfied with the thumbnails and go for the large final piece which will be a mixed medium of oil paints and special (expensive hard to find) colored pencils.
I may save up money and do the final piece on one of those expensive mega sized canvases, which would give me more room for all that awesome detail! =D
