Any tips or help would be great. I would love to have some supplemental drills for the Back Lever.

The hips are very piked in the front lever. It's ok for progressing to a true straddle front lever. You may want to see how you do with the 1 Leg Front Lever progression.

The back lever was better. Back support on the stall bars is a good assistance drill. Dynamic straight arm pulls such as skin the cat and 360 pulls can help as well.
