>>73>you have to find a demand and try to fill it rather than create a supply noone knows about.fuck that's wise.
and yeah, 3d form and force is paramount.
look into gesture drawing, your linework is fuzzy which is a sign of being uncomfortable with taking decisions with a pencil. The face and hands are nicely stylized and show actual potential in your drawing.
One example of what could be better is those straps on the handle should flow in the reverse direction, just like the line that depicts the skin stretched out from the guy's thumb to the finger. It would reinforce the direction of the cylinder that is the basic form 'underneath' the handle. As they are right now, the whole weapon looks flat.
Also, a succesful comic artist is less about anatomy and form actually, more about composition and the whole page/strip as one flow, one form that creates storytelling. Read Scott McCloud's books and learn about composition in cinema for example.
Still, actually making something on a regular basis is a good thing too, I'm paraphrasing: creativity must find you working. Carry a small sketchbook/stack of cards and write down your ideas, when you're out of ideas read that stack. Creating only fuels itself.
