Well, spriting is actually my thing, lol. Haven't done much devamping but it's pretty simple compared to revamping.
Before you sign me up as a spriter, however.. You should know that for some reason i can't put images in PMs or anything the likes, and the only way i can give images is by putting them in an Album. I was spriting for a game called BlackChrome and that is what i had to do. There is the obvious danger of people trying to steal my work, so i set the Album as ''only viewable by friends''. Now, this mightn't be such a big deal to you, that's great, but if you want the sprites to be exclusive to your game, then I just add you as a friend, create a new Album, set it to private, and then whala, exclusive sprites. For extra security, i delete the sprites when you've got them, lol.
Is this acceptable to you? Adding you as a friend will enable you to see a (tiny) portion of my work, too. If this is all a bit strange, i understand, but i'd love to sprite if you like.
