Looks very nice overall, I have yet to try it online, but it seems very good. 2 pictures.
This looks a little... wierd, and not real, I would consider changing that;

This kept catching my eye, I would suggest adding another layer, that is, intead of the direct slant, have the top layer, a second parallel layer a couple of inches lower, maybe just one, and than the slanted layer. This makes it a lot more realistic.
