Using Garry's mod, I decided to make a TF2 comic based on something that actually happened to me this past weekend.
Apologies if there are any brightness/lighting issues... this was waaayyy more time consuming than I had originally thought it would have been, and I'm certainly still no expert at Garry's Mod. After many tries, and being more nit-picky than I had ever thought I could be, I settled on the below. I have a new found respect for people who can create comics (drawing them or otherwise) on a regular basis.
