Its pretty good. What kind of Crayons did you use?
Oh, right on. Have you tried sharpening them?
Looks as good as many of the Star Wars insert cards we saw.
very well done, i like the shading alot as well
looks great! I didnt know that you did sketchs to! You should check out my thread, see if you can find anything that you like http://www.thedentedhelmet.com/showthread.php?t=33166
heres a little sampler that might catch your interest... maybe
I hope you dont mind a little tip but it seems that your sketch is a little crumpled, on your next one it would probably be better to try and avoid that but asides from that you've done an amazing job! keep it up
