Overall solid!. The spinal twist feels just right - not too much, not too little. Good cross contours too. Some muscles are feeling a bit out of proportion, notably the arm to the right - wrist is real thick, upper arm, deltoid a bit too arched. Remember to find the source of the curves - every curve of muscle will terminate or source to some point along the body. Find those source points (often landmarks but sometimes just a vector or notable curve) and use them to construct the musculature.
