Glowing Headcrabs ( uPDATED )

I put eye to these headcrabs so first of all you wont miss your target ( im very bad at aiming so i make this on purpose ) and it would look more like alien stuff..errr...YOU GET THE POINT>

*UPDATE NOTE: Added eyes for classic one. The skin as far as i remember is from cinematic mod guy or smthin XD sorry cant remember, just telling that i didnt make the headcrab classic skin, i only make the eye.
