I see what you're trying but keep in mind that the ankle extension you're using here is different from the ankle extension you'd see in a normal lift. It normally occurs with weight over the heels (dynamically), but you're coming up and forward onto your ankles. Your COG should stay over the heels, so you're actually changing the mechanics of the lift, causing more significant problems in the future.
Besides that, the snatch balances looked good. Try for full depth on the squat, though.
