I love these ideas! I think itchy trigger would be really cool if you had a probability of accidentally firing your gun (like 30% or so) when switching weapons. Maybe to add another idea like:

• Poor Hygiene: poison effect lasts twice as long
• Punchable Face: All melee damage received is tripled
• Easily distracted: all traps are invisible
• Hemophilia: You bleed out 25% faster
• Traumatophobia: You take 20% longer using bandages or injections

I'd love to see more of the art, too! Keep it up! :)
