I like the variety of subject matter in your sketchbook, especially the cartoon faces, the martial art poses and the "Random sketchy black and white concept thing." lol
Keep doing studies like Seage said, it really helps (I should do more myself ) and I'll have to try his advise about using bigger strokes with your arm...
And don't worry your sketchbook name is far more clever than mine. lol
