make your own watermark. please don't put an ugly dA advertisement on this great piece of artwork. type your name on the piece, make a mask out of it and invert the photo underneath -- people should remember YOU for this shot -- not some stupid dA commercial on a fantastic piece of art!
the composition is pretty odd imo, propably because that plane on the left side, destroys balance in the piece
all the rest is very emotional and clear
the plane on the to could be placed a little bit down also
