Also a possible suggestion for low health and buff:
(...) The dying/buff animation changes the shadow colour and increases the alpha for a second (usually invisible) shadow.
Thanks for the great suggestions!
I ended up animating it a bit differently, you can see the result in the newest version. The effect is pretty subtle now, but it should fit nicely with your pulsing hp cross.

These shadow pulses are also enabled for ammo counters now in that alt file.
The file that you want to replace is HudAnimations_tf in /scripts, the alt file begins with "SHADOWPULSE".
