nice effects could do with a border, and apart from blending the thingie coming from below the text, I don't think I have to offer any criticism
Make the C4D that is going from the left to right a little bit darker since it's not the main flow of the tag. Else, it's extremly hot.
Very nice job, especially for using such a crappy render.. I mean I hate sprites. First sig with a sprite in it that looks nice.
