Replying to LOOKING TO IMPROVE BIG THIS SEASON

So lately I've been trying to work on park . I had a knee operation so i missed out this season a lot but i came back at the end and started doing some park (jumps, boxes ) kind of rails . Ive always been more into mountain like 70% mtn 30% park but now I'm trying to step up my park game a lot this season about 50 and 50 . Is there anything i could start out with in park i like air more so I'm trying to get better at that . Or any tips you could pass on to a beginner to intermediate into park.
