looks pretty nice

i love the loadout screens, loadout menu, tourny spec ui
ingame hud reminds me of rayshud which looks great

Looks good, I love the match hud and health

Changes I would personally make if I used this hud:

i personally don't like the font for the health and ammos and how the match status looks, but i am sure a lot of people would like this hud

man when i see that "combo", "flank" and "pick" on class selection i hope this hud gets finished

most of my feedback is probably stupid, irrelevant, incorrect, and useless but here it is:

things i'd change:

i'd make the health and ammo closer to the crosshair, perhaps in a minmode toggle. i do know however that some people find numbers closer to the crosshair distracting, so you probably shouldn't.
i'd also make the font on everything that isn't the health and ammo completely different, otherwise perhaps choosing a font that is more "readable" (not that handel gothic isn't readable, rather other fonts are MORE readable than it). this could probably also be solved by making a seperate version of the font for the health and ammo specifically, and making that version "bold-er" if that makes any sense (it probably doesn't).
i'd also say to make things like displaying your name, profile picture, and friends list in the main menu optional, i hate seeing them, although this is honestly a nitpick and i'm probably just a loser.
on the topic of the main menu, making pretty much all the text larger there would be really nice.
i'd also use the colors for buffed and low health on spectator for playing, although you might already be doing this the screenshots don't show buffed or low health colors.
another thing id do is move the players in the spectator hud (the names on the left) more towards the vertical center of the screen, in these screenshots they are just slightly below being centered. again that probably doesn't make any sense and isn't helpful, so just move them upwards i guess.
on the loadout screen there are class icons, i'd say that making the spy his own face doesnt really work, and im pretty sure you could make it a knife and have it look quite a bit better, although this is probably another nitpick that doesnt particularly matter in the grand scheme of things.

things i like:

as mentioned previously i like the colors for buffed and low health in spectator
i also like what you've done for the specific classes in things like the class selection and backpack menu
i like the stats menu it looks really clean
i like the flat look of most materials, they look nice without using gradients or anything like that
for whatever reason i really like the default disguise menu, no clue why

thats all the feedback i have about the hud, feel free to disregard any/all of it as i'm not particularly good at tf2 and haven't actively played tf2 competitively outside of a few moments with friends. i'm also not very good at making huds and can only do a few things before asking for help so maybe i just don't know good ui design. hopefully this at least helped you in some way.

So ironically, I made almost all of these changes since the original screenshots; I'm just dumb & didn't realize all of these weren't updated LOL
I can for sure give the updated version, the Über & health overheal + lethal HP both do have animations; I will try to make gifs to show them off as well.

I will also take the screenshots you recommended - thank you sm for the feedback!!

P.S. I also forgot; the '6' was for the uber counter, which I actually took out, as I felt it was unnecessary

I think you mean this in a good way LOL
I have the beta version up on github, I don't mind sharing it here, but I update it extremely frequently lol

updated the screenshot album!
