Kazu's right--your character's personality is slightly odd. It reminds of of Bo-Bobo--what exactly determines when he goes "serious"? Is it completely random? Some indicating factor? You don't need it right away, but leaving other players with no idea how your character will react makes RPing slightly more difficult, see.
Alrighty, so your buster shoots... whips? Interesting. Do the whips go back to the blaster after firing, or do they--the physical thing's not that important, but might be a pain when you're trying to RP.
Mechanically, you're fine. It's just mostly RP fluff you've got.

Now, your Sig will be doing Wood type damage, unless you want it to do Null type (there's nearly no reason to do that, though).
Also, again for RP purposes we have a normal buster attack (Rapid) and a souped-up version (Charge). If you want, you can make the two as similar or as different as you want--just document it under Custom Weapon.
Got all that?
