I've actually got some constructive feedback, it's little things though:
Was skipping the usual red cross on heath items a design choice? I kinda miss it, perhaps if you added a cross-shaped strap over the lid it might have the right subconscious association without looking too anachronistic?
One of the things that I always get wrong with my models is not baking strong enough shading into them. Really make the lower surfaces dark. In fact, the best way to get that gemstone-like red bottle effect is to emphasis the dark colours over the light. I remember doing this years ago painting some High Elves, the closest I can find to the guide I had then is:

Finally, I worry a bit about distinguishing the 25 and 15 health packs, although I can see the different shapes and heights when they are next to each other, I worry that if I came to one in isolation I'd be unsure of how much it was worth. A few ideas:
� Make the cap on the 15 health pack more discoloured/mouldy/rotten.
� Push the colour of the rotten bottle away from red and towards brown (difficult to do subtle colour changes in quake, I know...)
� Only apply the super-secret twinkle shader effect to the two large bottles.
I'll expand more on that third option later, but one other idea I've had which may or may not work is this:
Take the highlights on the edges of the bottles, and colour (only) the adjacent borders of the bottle with dark orange fullbright colour. The intended effect is that in bright lighting this fullbright appears just a natural part of the shaded bottle face. In dark lighting these new edges appear fullbright, as if they were dimmer but still visible edge highlights, while the original highlights disappear in the dark.
