Pretty good study, I think the alien is looking good, if you pushed the darks a bit further, you might be able to achieve a little more depth. The third prawn lost a bit of detail, but Im going to assume that was just bad scan.
Anyways, keep up the good work!
Thanks for the review. Yea, I'm not very confident with darks. Compared to everyone else's work, mine always look grey. That third one is a bad scan. Shame.
