Hey KenSan, it seems to me that newish players see what other people are doing (on Instagram, etc), and "assume" , "ah, that's what I should be trying". When often, it's the newest, coolest tricks that everyone wants to try, even though they *may* be above their level. I recommend getting a solid grounding on all the lower level tricks, and then working your way up from there.
BUT having said that, different people find different tricks easier or harder, so who's to say which tricks you "should" be trying. Go for that Lunar! And those other stalls! Why not? If they prove to be too difficult for you... step down a level.
But always make sure that you're having FUN!
