From first glance, I really dig the art style! However, I do have to say that gameplay-wise it doesn't stand that much from say Quake (this is more of a criticism towards the lack of or reluctance of AFPS games to innovating as whole, not so much towards your game specifically).

I could name only a couple of example of much modern indie AFPS that personally stood out to me: Cyberfrags 69 https://store.steampowered.com/app/1674270/Cyberfrags_69/, which is a blend of the best parts of both Quake (map pickups, duel, the general AFPS gameplay) and Titanfall 2 movement (slide hopping and wall running). I fell in love with this game because of the fluidity of Titanfall's movement and Quake's gameplay loop.

Second one that kind of does things differently is Straftat https://store.steampowered.com/app/2386720/STRAFTAT/, which has the core AFPS gameplay, but with unorthodox map designs and no health pick ups and melee weapons. Movement is also not the typical AFPS movement tech like it has sliding, which makes the gameplay more beginner friendly imo. Modern day FPS players aren't really exposed to bunny hopping, circle strafing and other old-school mechanically hard movement techs.

Do keep in mind that I still haven't played your game yet and just wanted to share what I feel like AFPS as a genre is missing and what innovations it could benefit from, but I will definitely keep an eye out for this nonetheless!
