Wow!! You are improving very quickly! Your OLL is looking good, F2L is good, but your cross could improve. I had someone coach me on an mo3, and the main thing that I needed to improve was my cross. It really helped my times. So, for your cross, just make sure you are not still doing the "daisy cross" where you bring all the white pieces up the the yellow center, align them and move them down, that's very inefficient, so rather, do the white cross and I recommend J Perm's video that I will link. I found that this video helped me a ton too. Hope this helps you!
