7.7/10 - I like the style but after viewing all of your signatures it seemed a little repetitive. Try switching it up a little. But otherwise they are all great.
Kong sig- 8.5/10 The movie is blended nicely. The TRex render around it adds a nice effect. The left side brushing matches the TRex's skin tone and texture good but the right side brushing looks too rough. It doesn't seem to match Kong's soft fur that well. I don't like movie sigs anymore but my preference doesn't degrade the sigs quality. Good job. already rated your SW one way back.
8.5/10 Good sig but I think that lighting effect isn't right. 10/10 for the next one. great balance of light/dark areas. The lighting behind the render is really good.
10/10 lol awesome sprite sigs, do u do these in flash or photoshop? they must be a big burden to do it in ps
