They aren't very good, but I'll try to improve my skills... Please rate and comment ;]

Thanks, Helloxas.

First one is way too empty. It needs a bg

Second one.... Whats the focal? Not to be rude but it looks like a bunch of c4d thrown in

I like the subtle effects in 1st. Simple background looks good in this, but pure white is just boring, not simple. Try adding a good texture there, probably.
Text placement is way off. Never tuck it away in corner, it just distracts from focal. The first place coming to mind where text could placed is above and left from her shoulder, on intersection of thirds. (About rule of thirds for text: http://www.gfxvoid.com/forums/showthread.php?t=53968)

Second is kind of weird. Most of the tag is blured, the sharpened parts are placed randomly.

1st one needs a BG as shane said, and the 2nd one is cool, but the side border kinda kills it.

Thanks to all.

now it looks a lot better without that side border.

the new one is nice, but those effects are kinda over-sharpened.
