It feels like i can get deeper into turns when I lean back a little more
If that's the case, I'd take an intermediate/advanced lesson. Looks like you can ride quite confidently, but leaning back on a groomer with no fresh snow will hold you back. You've got to really ride the front of the board hard to start a turn...
Try slowing down a bit and really work on carving. Seems like your technique isn't bad, so slow down and perfect it!
