Thats pretty cool . Tips are experiment with patterns and colors and keep working on tags thats how you get better.
i like it. i think the colors are very nice. i might take that red stuff out of his mouth. its a good tag
eh i dont really like this one... dont really know what to say about it either i think you just started with a bad render?
