I hope you will like it, those are my first creations

I prefer the first wall, it's simple but nice.
For the second, the background is too simple, you need to add something.
Otherwise, i don't like the sign in the middle of the wall.

Your first wallpaper has a really nice design. I like the whole glowing rectangles effect, however you could make the white border a bit thinner, I think it overpowers the image its wrapped around. Also, I'm not really feeling the background texture. That could use a bit more work.

For your second one, it doesn't seem to be balanced, all the focus is on the left side of the wallpaper. The text does sort of act well to balance the wall, but it's not enough. I would suggest adding something to the right side or maybe making the image smaller and a bit closer to the text. Also, the background stands out too much. The pattern is lovely, however you could tone down the opacity a bit, so it doesn't take away from the main focus, which is your image. I hope this helps! =]
