Haven't had too much time to work on anything because of the holidays, but I went back and thought about some abilities the character could have since I had NO idea what direction I wanted to go in before.
I sketched out a couple ideas for one of them:
The idea would be that the character beats on the drum (that is filled with static electricity, and sounding similar to thunder), which in turn charges her weapon(s) with electricity.
Other ideas I've been thinking about include a static electric "force field", guns that shoot balls of electricity that'll explode out similar to fireworks, and a lantern (like a bug zapper) that either is the weapon or charges other weapons. Did some extremely rough sketches, mainly just to get the idea down:
I'll explore those more in the thumbnail stage, and if they make it past that point I'll decide if I need to do character sketches before the final!
Time to move onto thumbnailing!
