You pulled off that infected look with the dark veins and the blood red eye.
It reminds me of 28 weeks later. Zoey was left 4 dead! ;P
Cons:
I'm not sure if this is just me, but I couldn't get the red eye to appear without editing.
Conclusion:
To get the red eye to work, I had to rename "teenangst_eyeball_l.vmt" and "teenangst_eyeball_r.vmt" to "zoey_eye_l.vmt" and "zoey_eye_r.vmt" respectively. (This also conflicts with "original_l4d1_melee." You can fix this by removing Zoey's eyes and head files from the "original_l4d1_melee.vpk" and then repackage.)
Otherwise, well done! It's a nice touch and the effort shows. :)
