Critique wanted, eh? I'd say you're on the path to greatness, but you must first take the path filled with obstacles. Practice lone feral lizards, such as this one. Get a feel for their scales, the bends of their bodies, the shape of their claws. Then play around with clothing. Try drawing clothes alone, from references, on random things. Then finally, turn your practice into it's final stage, practicing poses of human qualities. If you take this road, you will one day draw this again and giggle at what you drew before.
