First two of your art nude have some good things going on. The rest of your portfolio is utterly and unfortunately different. If those two are your latest, then I think you've turned a corner in a positive new direction as the other stuff is either poorly lit, cheesy, dull, weird ( but not in an original way) or boring.
I think PP hits on a good point. Often a complete change of direction proves to be a rewarding exercise. Perhaps revert to a completely clean slate and moving forward only choose models who will challenge your current perceptions of what model photography is all about. Don't resort to shooting just for the sake of it - be selective and picky. Be adventurous and take a few risks. Be inspired by broadening your horizons.
Easier said than done but FWIW those are my thoughts. Good luck
