How to get better at megaminx?

[MiaSponseller]

I've been into megaminx since spring and have dropped my times from 3:00 to 1:25. Any tips for getting faster? I know the last layer algs from Odder's Megaminx guide. I orient edges, then corners, then I permute the edges and permute the corners. I know three cases for permuting the corners and then I use commutators for the rest.
