I really like #1 ... the radial streams of water combine nicely with (it appears) the horizontal droplets. There's *just* enough motion blur for those to be interesting. The soft focus in the BG lets us know there are trees but doesn't distract us with them. Did you sepia-tone this pic? If so, that feels just about right to me. And I like the placement of the little boy. We look at this pic and it captures just the mood that (I assume) was intended. Nicely done!
BTW I shoot a D3200 as well, and am just starting out. Best of luck to you!
