Since you said you wanted some criticism, I’ll have a go.
As I already mentioned, you’re using the default phys for TF2 ragdolls. They’re very hard to pose properly, which is why everybody uses Nexus’ enhanced phys. While you managed to get a good pose on both Soldiers, the pyro and the heavy, the spy looks really awkward and the scout is really odd - there doesn’t seem to be a way for him to jump up like that. In addition, don’t use emitters, they’re not exactly made for posing purposes.
Other than that, your poses are pretty well done for using the default phys and the editing is good too. You’re off to a pretty good start.
I look forward to more of your work.

Also, non-TF2 maps are generally not very good for TF2 poses, obviously. I know TF2 maps crash in gmod right now, but ctf maps still work.
