JarateKingGreen is a hard color to get right. I like it done well, but done well is completely dependent on the monitor and the lighting you're in. And how finetuned it needs to be to look good means green on one monitor looks fine, but looks bad on another. I like the look of yours on my phone for example, but not on my laptop.
Imo the biggest advantage of a healthcross, in terms of design, is that it makes symmetry make a lot more sense. It's a lot easier to get healthcross + health look consistently spaced with ammoclip + reserve than it is without the healthcross. But imo it just looks a bit off if you don't organize it some way; maybe make the separation between the health and healthcross the same as the ammo's, or maybe move the reserve up and to the right so that it's centered the same way as the healthcross is. It doesn't look bad what you've got, but they look better by themselves than together, if that makes sense.
I can't say I'm a huge fan of the uber flash, purple doesn't really show up anywhere else and feels out-of-the-blue. I'm assuming it's there for a huge contrast, but it doesn't make sense visually. Something like, for example:would be just as (or potentially more) flashy and noticeable, but not clash with the theme you've got going currently. Rainbows are a nice option too, though they can be hard to tune well.green -(slow transition)-> dark green -(fast)-> white -(slow)-> green
I'm not feeling the right-only shadows too. I like straight down shadows, and that's pretty uncommon in a lot of huds, but rightwards I've only seen rightwards in one or two other huds. This is entirely opinion though.
And it's just a small observation, but it's completely possible to remove the - on the damage number below the crosshair with a custom font, if you're feeling limited by that. I always do that on my own huds at least, I think it looks more clean, and to get it to align properly for any number of digits with the - removed is very easy. to get it aligned the way you do with the - for every damage number possible would take much more work and weird workarounds (enough that most hud makers would say you can't).
I do have to say that the font choice, cp icons, and the round/game timer (the positioning and sizing in particular) are all on point.
wow, thanks so much for this large critique :D it means a lot that you took time to write all of this. i will take all of it into consideration!
