No, it's definitely not a good first try. Decapping yourself is never good.
Ohai, here's a bad replay because i decapped myself.
That aside, it's pretty decent for a first time replay, but compared to other things...
It's stiff, robotic and you don't use a lot of joints at a time. The latter isn't always
bad, but if it's in conjunction with hold all, it usually is.
But keep on practicing, it can only go up from here ^_^
