@Hasea nice setup, i like it, though the arms look weird, i don't think you had to raise and extend them all the way up to land the trick
The rotation was cool
The landing looked awkward because you landed on a fully contracted hip and didn't extend it afterwards to stand straight up :/ (This is probably a fault of not enough rotation)
As for the abs, i usually keep them on hold in the contracted position and rarely extend them, i don't think they're used frequently in tricking, but i may be wrong D: just use them whenever you think you should : D
overall goodjob ; D
