Paulo, Wonderful capture. I love the composition of the shot. A couple of changes I would make for the final photo. I would change the crop a bit. Take about 1/3 of the bottom off and put a bit more of the top. The bottom has way to much negitive space and makes the viewers eye fixate on the dark region of the photo. and with the top cropped the low it gives off a cramped feeling. By changing the composition of the shot and elminiate the situation!
