This is an angry man who seems to be yelling. There should be more attention to detail and color in this piece of art.

Differant

Ok so this is kinda interesting, it is some sorta drawing and or sketch, he is screamming something so you did show some "EMOTION" in the art piece and thats always something i look for, you could have done abit more with the white backround though, aswell as throw in some color maybe even multiple colors, seems kinda silly with him so angry, but i found it kind of interesting but seems to need more effort regardless.

~~THINGS TO IMPROVE ON~~
could have done abit more with the white backround maybe some color base, so that you can have more focus on the character itself, and a touch of color in the sketch is also needed.

GYAAAAAAAAAAAAAAHHHFG

that what i imagine him saying

Arghh

This would seriously scare the sshh out of me in real life
