Eh. Okay i'll give it this - for a railgun this actually not that bad. Only problem is that you should've played with light near handle to make middle part more wider - you need space for both anode and kathode and carrier of charge to speed up.
so im going to guess that either A, that energy meter type thing at the end is either an actual meter or B, this is some kind of hardcore magnetic repulsion recoil rifle? either way, a decently drawn gun with good detail.
Nice rail gun- but shouldn't there be some sort of optics mounted on top for long range shots? I like the external power pack- many laser guns in SF have external power packs, just like this rail rifle. You might wear it on your hip or on a belt. Just don't get the superconducting cord tangled.
