I see nothing major as to things being wrong with it. Although it would seem as though you tried to fill space by stretching your render or the render doesnt fit. The left side seems empty even though you have something there try to make it at 350 px in length. Text over a render isnt always a good idea seeing how the render is usually your vokal point....but for your first I think you did a good job.
