That's great. Has a lot of potential for a series (I can see those guys somehow managing to survive the death star being ejected among the debris). You MUST know about the space janitors series on youtube at geek and sundry right? If not check it out.. it's about two janitors on the deathstar (kind of.. it's made to not violate copy right so it's more of a doughnut) and I can see big cross over potential.
keep up the good work!
