I did a Star Trek vs Alien comic on You Tube but I was inspired by the star Trek motion comic which was far superior. I expect you can still find it on You Tube. My only criticism was that it had more Alien than Star Trek.. watch it and see what I mean!
For my part I just wanted to do feature an amalgam universe featuring as many different classic sci fi elements as I could squeeze in. Working on the final part of the second story now. It's fun to make! Not sure if it's fun to read lol.
