Star Trek: The Animated series

So here's my first attempt at a poster for potential new animated series, featuring my new design of the Enterprise-A. It's made me realise that I'm totally lame at characters! I've used the basis of a couple of characters from the Disney Infinity games and changed them to more closely resemble Kirk and Spock. Whilst I'm quite happy with how Kirk turned out, I'm not so happy with Spock. Any good CG character designers out there wanna pitch in? I'm envisioning a Star Trek animated series similar in style to 'Star Wars Rebels'.
