ur stuff is really good but i think you should go back and do some anatomy studies of the torso, just so your charaters look more graceful and less stiff.
but you doing good n i really like that landscape on ur IM post it here .

man you have got so much better since the start of your sketchbook, i didnt look at it all but skipped through it, some really amazing stuff...my sketchbook is on my apge or something if you wanna check it out, i haven't updated it in ages, but i might just do that soon
Just a few things to look at.. perspective issues like the scythe guy can be avoided a lot better if you draw the character after establishing the horizon line and whatnot, instead of fully rendering a character then sticking the perspective guides in afterwards.
And on that vein, try not to get in a habit of just sticking characters on a blank canvas with no background. It's easy to do and hard to break (I struggle with this fiercely, myself :o ). Try doing a quick sketch of everything right off the bat. It's fun to get detailed and render the crap out of anything, but a little elbow grease in the preliminary stage can save a ton of headaches in the end.
very nice character designs man especially from someone your age. good stuff. only thing i can say is in some of them the hands looks like they were giving you trouble and some could also use more darker tones. but great stuff.
