You were definitely going for the grab to much on the second stock. A wolf like Kosk will expect it and know when it comes out. Try jab-->grab, nair-->grab,lazer-->grab, and so on.
Your SHDL's were a bit high. Delay until close to the apex of a SH and then lazer. Also, you have lazers for a reason. You can combo a lazer into many things. Watch a few of SK92's vids, he uses his lazers amazingly.
Work on your boost pivot grab. You'll always want to have that down in case you come upon a situation where it is needed.
Other than that, pretty good. Your mindgames are great, and you're not one of those spammy falcos.
But yeah, lots of **** going on.
