It has an extremely interesting look in the side shot, and I like the way you built around that canopy piece, but from the top it looks sort of plain. Some greebling on the pincer arms might help, as would a couple of small vertical fins, but overall I like this a lot. Nice work.
Could be used in a ground battle as a minifig-snatcher... just grab on to the enemy's commander and drop him in the middle of your base.
Just one random act of violence can brighten your day. Especially if it involves explosives.
