the first looks nice, the second i am liking the background but the text and the cut out of you (i'm guessing its you) are not really making me wanna look at it, the image of you is quite messy on the cuts, doesn't look like its part of the picture, and the text doesn't go well with the background.

How to Fix:
Portrait: the image can be cut a lot smoother by using the poly lasso tool, and zooming into the edges, the hair has a lot of detail so you will need to take you time and cut, but also using a feather will help make the hair blend.

Text: the dark shadow and gradient doesn't look right at all, its quite off putting in my opinion, this could be fixed by having it as a plain text and maybe a little stroke on the titles.
