we like how urban and simple are different in weight. would you try some other fonts? the "u" should be fantastic, and please don't be afraid to use more design elements, like a texture or gradient on the box the U is in. Maybe play with inner drop shadow on the u... and try the box with sharp corners and maybe in a circle.
Keep in mind, the "u" has to be in the same font as "urbansimple". We want a clean, unique font... nothing weird, but unique. So you should try other fonts for the entire logo.
Also, please try other "boxes" without that busy design in the background. Just want to see other versions.
