Next time you're doing photo manipulations do your best to find really HQ images because the ones you've used has really bad quality or you have messed them up throughout the editing process.
Also it looks really unrealistic because there's just some water splashes going up the dress but none of them are in the water, so that makes me think how did that even happen? No laws of physics at all.
It seems that you've used too much HDR effect too, the splashes of water especially seems cartoon-like.
