Level up!
Well, that's a pretty damned good piece of had drawn art I just saw there! Though I'm not quite sure what the background is, you've certainly gone to town on the production of the character. The detail is exquisite - from the strapping on the arm, to the occasional blemish on the leather strap for the sword and the creases in the clothing.
You've found a nice tone for the flesh and I think this is the crowning glory of the piece, as so many aspiring artists fail to get a decent tone for standard skin - it's either too pink, or too pale, but you've got the balance there, with a little orange added in places, which could easily be passed off as arm hair, judging by his hair colour in the piece :P
I think that there could have been more detail in the right shoulder, as it doesn't quite look buff enough for the rest of the body. I know that it's hiding behind the torn sleeves on the vest, but it might make more impact if there were a little more muscle tone detail there. The same can be said for that right arm - muscles that big tend to have bulging veins along them, so one or two, just for an additional insight would work tremendously.
Finally, I'd suggest something with the hair - it doesn't look realistic enough for me - you've coloured it as if it was one swathe of colour, in the same way (and colour!) as his shirt. Directional colouring can create the effect that the hair is actually composed from your pencil strokes, giving the impression of more hairs than are actually outlined.
Good luck with the sketchbook tour!
