Honestly, one of the very hardest parts of making art is just getting over the mental block of 'I can't/not good enough'. Making art is a declarative thing; you're asserting yourself over blank paper/canvas/pixels. It is always a good thing to do! KG, your arts make me grin.
Less seriously, I just had the randomest turian musing come to mind. Mandibles. We always see them move together as a mirrored pair, right? Always/almost always? D'ya suppose with some concious effort a turian could move his mandibles independently of one another, like one going up and one going down, or one holding still while he waves the other around?
.....yeah.... I do not know what prompted this.
