Nifty sketch
~~REVIEW~~
Ok so here was something, is it a ghost maybe not so sure, to be honest it looks like a guy with a gas mask on or something, hehe but anyways as for your sketch here the pecil work seems pretty good, maybe abit too dark at times, but still ok, i think you should have done something with the "EYES" like have them a differant color, maybe a green or blue something that sets them apart from the rest of the drawing but anyways, you do have a nice drawing here, i like that you had some backround and all, anyways nice job.
~~THINGS TO IMPROVE ON~~
ad something to the eyes maybe a differant color or something
