A bit monotone, pretty nice background though. The right side is a bit empty, and the text seems cramped, main 2 things you need to work on here is effects on the right, and some more depth. Check out some tutorials for depth, and maybe try smudging the right a little bit. Nice concept though .
I think the right side is allright and I guess you meant the left side. Well, just remove the text and add some effects at the left side. It is too empty. Improve your work on depth as Fallen said AND on lighting.^^
without the border is best imo. the left is a little to blury and the text needs moving. Nice render good job
