I still like entry 33 the best as i prefer to have the "X" remaining an "X". Could you try to do the logo in 3D? and could you do the X two colored and also 3D? Maybe some uneven "X"? The "Frac" looks better in blue, forget about the black. Also, the ".com" needs to be in like is done in the new entries. Can you add the tag line, too?
Thank you!
