This is beautifully done. The composition is pretty good, although you could of included the rest of the dolphins head. It just seems to be cropped off OR keep it, gives it balance with the fin cropped off. Nice usage for the water affect. It would be nice with a one inch border around the whole drawing. It adds more to the composition of the drawing. Also gives it a professional studio framed look without having a frame. Many artists include a one inch border for presented final works. Think about it. Very good job indeed. Keep up the good work.
