Sorry if this is the wrong place to put this, I didn't see anything in the stickies. I DO have art to post, so I think it's ok to post here.

I have a Deviantart account, and after not having drawn for over a year, I've been practicing drawing again. I've been trying some of my favorite Pokemon for a while. Lucario is one of my favorite Pokemon of all, and I've been wanting to draw him for a long time. Unforunately, he is one that I'm having a great difficulty drawing. I want my final drawing to be this really neat battle pose I have in my head, but I want it to be the best drawing I've ever done. Above are links to three sketch sessions I have, drawing him and different of his body parts like his legs. Is there any advice you could give to me? Is there something I'm doing wrong?

1st, if you're practicing then use a pencil not a pen (Even if you can get clear drawings out of a pen).

Other than that i can tell you to work on proportions, until now its ok but i think it looks sort of a bit way too large.

I suggest using basic shapes as the base of your drawing, like a circle for the head and work from there. And as mentioned, please use pencil instead.
