Um, don't use the blue gradient background. I had to read squint to read the first three lines, which ironically are usually/should really be the more important lines.
If you must use a gradient background, use one that's a lot
lighter, or use one that does not dilute any of the writings.
The tabs on top, i.e., "Home", "Gallery", etc., have white lateral sides -- are those intentional? You may want to remove those. You may also want to give more space on top and beneath those tabs, to give a cleaner feel.
Good work though. Keep it up.
