Looks good so far! I know you said you'll change the green once you finished but I also agree that it is too light at the moment.
But yeah, don't go overboard with the highlighting. Also just because that's how Habbo has designed the feet (with no proper toes), don't let that stop you from going ahead and making your own feet. It'll look much better in the end! But overall, I really like it and it's much better than some of the Hulk alts I did back in the day. Keep on working on it and keeping us updated :-)
Off topic but @MONEYMAGIC, I remember making those Wiggles alts years ago! It's good to see you are still using it :-D
