Bloodsucker

I am currently completing a challenge to learn and improve my pixel art skills.
A challenge to make an animation each day for a whole year (Telepurte challenge, if you will), starting from 06.06.2022.
This is animation number 2, Bloodsucker from S.T.A.L.K.E.R, made on 07 Jun 2022.
Some animations I may improve/rework if I'm not too happy with the result.
This one I most likely won't redo.
