Even though it's a small edit, i may change the tie color for the business suit to fit the BLU Spy, or you could do it if you can, then people could use the regular business suit for the RED Spy, or the blue business suit for the BLU Spy :D
Also, you should do as Skele said and put the 13 Dr. Who shirts in a seperate .zip
I like the TF2 ones, but why are the Soldier's eyes closed? If you look under his helmet, you can see his eyes are open
