Here is a tip if somebody wants to make a Garry's Mod comic: First spawn a big plate (they're under 'construction' in the props spawning menu) and freeze it into place. Then set up your pose on top and maybe a camera too, then parent everything to the plate. That way you can just move the plate around to get a better background without having to rearrange everything, because once I set up everything then realized it would look better if I turned it around, and there were many things to move. Then when its in a good place just use the color tool to set it (the plate, I mean) to invisible.
Though its a good idea to be careful, because one time I parented I think an NPC to the plate and it went spinning out of control and I said out loud "OH CRAP COME BACK"... it was quite amusing.
