Nice handling of the highlights in that skateboard study; the blue-ish tone of them contrasts nicely with the base skin tone.

I'm no perspective expert, but your perspective sketches look nicely framed in general. It's really easy to place the vanishing points too close, or crop the picture too far from the horizon line and end up with serious distortions at all edges of the picture (especially if you're me, LOL), but you seem to have a good feel for it.
