I think you over did it with the skin touch up. Maybe mask it down so that the parts touching the floor and more sharp. Or bring down the opacity a bit to show more of the skin texture. I don't think that is an appropriate stage for a glamour shot. Thats why I would drop the High Pro Glow down a bit.

But over all it is a nice composition. Nice model solid background, some light here and there. Just sharping up the edges. woot woot.
