*Gulp* Runescape.
OK, whatever. About the drawings, your shading is pretty good but I'm afraid that's pretty much only good thing on your drawings. The people in the pcitures are standing like they were ready for 3D modelling purposes. Try drawing some people in dynamic poses. About the anatomy... Ugh, arms too short, hands aren't bent in any way, bad neck to head connecting, flat looking faces with practically no shading, in the second one, the bag and the axe he's holding would fall down if he/she was really holding them like he/she does it in the picture and also his legs look like they were bound together by duct tape. In my opinion, the knight's way better than the second one.
Other than that, keep experimenting.
