Forest Undertaker and Sketches

Welcome!  I've got a fairly rough character sketch for an evil forest dwelling undertaker type that came out from lucrative sketching process.  I've committed to making a dramatic action to reveal his powers and could use some critiques before moving forward! 

I'm currently hoping it reads as - I'm being attacked!  Wtf is that thing?  Oh, that evil branch-faced dude is responsible. 

I've also got a few more sketches.  The first, play (well studying...) at the park, then a beer themed party, and sketches of animal miniatures.
