Maybe change the crate to a TF2 crate instead? or possibly even a custom modeled one. I feel like valve wouldn't be that keen on accepting it if it uses HL assets, as far as I know anyway

Making it loop would also be a good idea if you havent done that already, its kinda hard to tell

maybe give heavy a book relating to Russian philosophy or literature? he does have a PHD in it, and would add alot to the taunt IMO. though would probably lose the cool reference to a certain statute that I assume this taunt is based on.

I know I know, its a old taunt that hasn't been updated in awhile but still, these are just ideas I'm throwing out there
