hmm lets see...
the first is ok, a bit random maybe and i think youve got to much text on there but hey its ok your just experimenting which is the best thing to do with PS.

second one i quite like, nice shape to it it works quite nicely - maybe have a more colourful background image other than the squares other than that it looks quite nice

3rd one is pretty cool the shape is nice shape but its a bit to blended with the background and the 4th well um lets think...its very star like!
