MASTERPIECE ! :D
Since i saw the gameplay trailer for Overwatch i waited until someone made that hud for TF2. I currently use it and it's m favorite hud at the moment.
But still, there's some things that should change/get improved:

-The map name on the loading screen gets behind the loading box (you know, the one that says that the server is VAC secured) (i play on a 1366x768 screen), map name should be on the left side.

-Add more menu backgrounds. Ex.:
Forest: cp_gorge, cp_mountainlab
Jungle: pl_borneo
Ice/Snow: cp_coldfront, pl_snowycoast
City: pd_watergate, koth_king
Badlands: pl_upward, pl_goldrush

-The classes portraits on the loadout menu would look better with other cosmetics (i know you used the pictures on the Tipped Lid TF2 wiki page). Ex.:
Scout: Brotherhood of Arms / Front Runner
Soldier: Team Captain / Killer's Kabuto
Pyro: Napper's Respite / Brigade Helm
Demoman: Scotch Bonnet / Glengarry Bonnet
Heavy: Officer's Ushanka / Tough Guy's Toque
Engineer: Texas Ten Gallon / Hot Rod
Medic: Surgeon's Stahlhelm / Vintage Tyrolean
Sniper: Anger / Swagman's Swatter
Spy: Fancy Fedora / Charmer's Chapeau‎

If there's a way to do it by myself, please reply.
