I'm just guessing here, but judging from the hole in the ground and the damage to the airplane, you're getting "up" and "down" mixed up when you're inverted.. Learning to fly inverted can be a pita....
I had the same problem when I was learning.. If you think about it, the reverse wingover is just a "modified" overhead 8 and/or visa versa.. After planting the second airplane while learning the reverse wingover, I quit trying to learn the maneuvers in order. I went to the overhead 8.. Once I mastered it, I then went back to the reverse wingover..
Something else that might help you. While learning these maneuvers, don't worry about the bottom height. Make the maneuvers BIG and keep the bottoms high -- 10 - 11 feet high.. This will give you some "headroom" if you should make a bobble. Once you have learned the basic "stick movements", you can work on the size, height, turn radius, etc..
