I started 7k with arrows skin, and I was with that skin for a long time, until I changed to the skin of this guy https://osu.ppy.sh/users/1326008 to start to play 10k, (since my old skin don't have 10k skinned) and I liked it, so I changed for his skin. The problem is, I sometimes can't keeping up with the notes, even on beatmaps that I already have passed before. I think I'm with this new skin for 1 month or more and didn't get used to this skin yet, but 1 month isn't much time? I think my brain is missing out the shapes of the notes, because on my old skin the notes have diferent shapes, so what I do? I really want some help because I stopped completly to improving for any other key modes that is not 4k
