Ok i need some help with some prespective...

Now this arm.. i want it to look like he is looking at his fingers in a clenched hand sorta way... now my problem comes in the fact i cant make the arm look right with clothing... it tends to look like i just glued it on or something.
secondly i cant get the damn hand to look right i know it needs the knuckels shown from that perspective and not the fingertips but its just not coming together

also i realy want to do this drawing... its far better then the previous one i did >.>
EDIT:
Never mind worked it out myself
