Hello! Super-duper newbie to SFM =P But I wanted to ask for some advice since my ultimate goal for SFM is rather specific

Did a bit of a silly doodle for TF2 that turned out surprisingly popular and it sparked a rather cute short movie to me, involving the TF2 senty and the Portal turret.

I've downloaded and installed the excellent Personality Turret workshop file, but I was wondering on how best to make it walk believably, perhaps climb, and if there is a similar way to give the TF2 sentry a bit more life than its pre-set animations allow it?

Any help is welcome ^.^ Sorry if these are dumb questions
