Amazing gameplay and aesthetics. Very well done. Safe to say that you can now (if you don't already) call yourself a professional level designer :)
Stunning map presentation, reminds me of de_blackgold from CSGO. Also makes me want to play Mannpower for once, PD suits it better than CTF. I loved the vertical play with grappling hooks more than official maps. It feels like an actual trade off between mobility and being combat ready because of CQB and upper platforms to reach. Not to mention the fighting happens quicker than on CTF. Gump better find its way into an official update.
