The first one:
The render is ok, but I don't like that wave effect on it. The border could need some work, try adding more details. Text doesn't fit.. I would like another font and another color, make it fit with the border.

Second one:
Hehe, very simple, could be made in one minute.. Though I like that it's so plain. It's not ugly, you know. The text doesn't fit too well though. Change it and it will look like some website header or something. :P
