I don't like the way you created the second one, It look's like to mainstream "standard" compared to the first diagonal design. The two black stripes upside and down, breaks the style in the 1th one too, like just cutted the slide from the second one to make the first. Maybe you should merge a mask or something to the 1th, or just cut a little bit the edges to make a more clean way layout. /just saying.
I really like the first one's shape, simply because it's something less normal and I find boxes to be too uniform and straitlaced; I hate having avatars that are just perfect squares, I like renders with different shapes and whatnot. /tangent Also, wow, the background is beautiful. I'm pretty new to Photoshop myself, mind giving me a few tips to create some effects like that?
