Nice strokes. What I wouldnt give for a hitting partner that understands the term "rally". Some think it means try to hit a winner every shot.
I watched it a few times and most of the time the backhand appears to cross the net higher than the forehand. THere are some shots where the forehand does cross the net higher but a few shots is goes in the net. Anyhow more topspin will give you more clearance over the net and more safety/ consistency.
Anyhow here is a vid that helped me get the "modern" forehand and should help you with the spin
