Firstly your photography is pretty good. It would be better if you could find a way to eliminate shadows and to not have your creation diagonally orientated in the picture. The piano is nice but I'm not too sure what that round 4x4 flat brick is doing on the bottom with the turntable connecter. One thing you could do to improve this put some black cheese slopes on the sides to give it some curvature like a real piano. Also don't use the smaller pictures for creations, the full size centered pictures don't put too much emphasis on the text and people don't go mad trying to see the creation. All in all it's a good build and a good step on the way to becoming a great MOCer.
