Funky?
I am sorry but where is the funk? He needs to be getting down to some funky fresh beats if he has the funky. I don't even know what you were going with this one, but I do like the character. He has a personality, with those lost teeth and wide eyed smile. I love all the weapons he has and the details on them. I think the thing at the bottom is tacks? I don't really know. I'd make a point to make that a little more clear when you're adding something so small, just give more details or more text for realization of what the item is. I think that the one arm is far far too long for his body. I mean, it just comes out of no-where and then his other one is kept inside. I know you wanted him to extended his arm to hold things, but it seems very off proportions compared to the other arm. I think you really need to work on body positions of the characters you create originally, but nothing too bad, just for arms in this one. I think the overall body and character you've created in nice, but I would have loved to see this in color or with a background. You would really have spiced this up from just a doodle to a nice art submission going the extra mile in detail and colorization. Overall I do like the characters that you come up with tho.
~~THINGS TO IMPROVE ON~~
Add a background, add color, and fix the size of that extended arm.
