It definitely is a work in progress, and I also see a lot of potential in the way your draw if this is a first attempt, it was done quite alright. What I would suggest is lightly sketch out the drawing first, that way if you make a mistake it would be much easier to erase.
Also try to proportion the legs so that it doesn't look like he's got short stubby legs and a long upper body. All in all, it's still quite good for a first attempt.
