I have a little bit of criticism, although it's mostly due to my own preferences rather than it necessarily being a bad thing.
I've noticed that the font used for the Health and Ammo numbers is also the main font for most other parts of the HUD.
Example:

Now, whereas in some places this font looks okay, in others it comes out pretty ugly looking, whether it's too small to properly see (for example, Jump iT Server timers) or too big (hovering over someone's spray, displaying the user who sprayed it). In the above picture, the "DEMOMAN (129 ITEMS IN INVENTORY)" is fine, but "BACKPACK" is a little too small for the font and it comes out quite ugly.
I was wondering if this is something you were going to work on changing, or if it's worth changing myself. I'm not sure if I'm the only person who thinks this particular font doesn't work well in certain places, but if I am, I have no problem setting it to a different font myself.
