Wow! This is so amazing, I don't know where to start

First of all, I really like how you applied the watercolors, especially the greens. Each is layered to give a soft feel as well as a particular sort of depth. The river is lovely, and the foliage overall turned out simply yet very picturesque. You put really good use of space as well for the trees, as if to look at a little humble park in a foggy morning.

Of all the things in this picture, the part of it that turned out the best is the bridge. You seem to not feel obligated to draw/paint out every single rock in its structure, yet the simplicity applied really brought forth its texture. The plants growing around it is a very nice touch, giving it a very natural feel.

The boy himself is very cute . He looks very relaxed, and the way he's clothed and seated gives him a very laid-back disposition. Perhaps there is a bit of a problem with how he's is drawn seated, however--his pose seems to suggest he's seated with his butt hanging out, like he's sitting on the rail; if that is the case, his arms look a little too relaxed as sitting with your butt out throws out your center of gravity, resulting in one's arms gripping the rail harder to compensate for loss of balance. If, otherwise, he's seated on a rail-less bridge, and/or the bridge itself is a flat, paved road, then I'm rather curious as to why he seems to lean so far forward with his arms straight out (doing so could result in falling forward). Lastly, I'm not sure if it's the bridge or his clothes that are hanging over between his legs, which bothers me some as that spot is close to the very center of the picture.

All in all, however, everything here is so beautifully painted and put together. The placement of everything gives a relaxing feel, and the textures add a rather serene atmosphere to this humble painting. Everything here is well done, and I applaud you. Great job, and keep up the good work!
