im not sure that all the angles are working. try to fix the chairs back. also the girl seems to small compared to the chair.

Thanks for your comments. I will change.

Reflection needs to be stronger or needs a shadow.Her feet looks like they are floating.

this is much better but the chair needs to be fixed still. try using the distort transform tool on the back of the chair.

Agrees with jaescoe21 but if your floor is a single layer, just put it in a tighter perspective with free transform and it will add more depth. It just looks like she's hanging on a wall.
