well i think you should just start over it is far from being saved but
his weapon is a tablet pen? that is retarded sorry to say. you could at least change it so it is actually a weapon that looks like a pen instead of having a big pointless pen that he is using instead of using is brain and just grabbing a sword or mace.
he is wearing a cape? whats the point of that? maybe if he was wearing clothing that went with it
he is wearing knee pads? is he a a construction worker?
the gloves are black for no reason also. everything is unconsistant. the lighting is way off. looks unrealistic. you pasted him 2 times in the background which is ugly and unappealing(3 times more ugly than needed) he looks like a special needs person.
the proportions are way off maybe look at someone on google or leonardo sketches. what is with his shoes? does he have cancer in his toes and needs special boots?
he has a logo or symbol on his chest. that is kinda cool if you are obsessed with newgrounds but why would it be so small? i doubt the character is going to be that size in a game so you may as well make it bigger so you can actually see it when he is resized.
the shirt sleeves are inconsistent as i said before. one is short and one is long, and the left sleeve should be hanging below the arm from gravity
i would look at an object or person in real life to see how shadows really work. they arent just a big circle below you they are bolder the nearer the object is to the shadow. also they make the same shape as the object depending on the light source
