I'm red-green colorblind, so I have some difficulty with several of the pickup icons. Specifically, the fire, poison, and stun flasks all look the same to me, as do the freeze and shock flasks. Since all of the statuses already have associated symbols, I suggest you put them in the background or 'corner' of the icons.
I started trying to make a couple of examples in paint, but it wasn't going too well. My wife looks over and asks what I'm doing. I give her a brief explanation and she says "oh, I'll do it in illustrator." So 20 minutes later I have not an example or two, but a full new set of icons. Feel free to use these. I can also provide the file in .ai or .svg format if you'd like.
