Grab your weapon

Phew, do you know that feeling when you have so much stuff to do and don't know where to start? It sucks, doesn't it? Well, for tonight I decided not doing any from my to-do list, instead I was drawing a little. This is the first few of the weapons' concept art I'm gonna make.

And yes, I know I promised a tutorial, but turns out my microphone is a regular cheap-ass one - you know, the ones that after a year or two turn into an extraterrestial-communicator-unit (too much unidentified alien noise and sound) :)
So I bought a better one which I'm also gonna use for dubbing and probably for sound effects as well, but I'm still waiting for it.
