Good, I can see where your coming from it has a small likeness to him, what can I say to help well make sure you set out properly have scrap paper by you put it on the paortrait and draw the right eye here again then lower it about 1 centmetre I hope thats a 1/4 of an inch then the other eye have a look as I thik you draw the eyes one at a time in stead of together your basic drawing of eyes noes and mouth are good but the placement of these is a little out and when your drawing you will think of each small piece in stead of dioing that artist thing of stepping back say 2 metres and having a look at the overall work I do it now all the time its a part of me. Here the head tilt is different to the eyes, only by a degress or two but enought to throw you out. Good luck keep going you are good at drawing the features and the likeness will come. Good luck, remember it's the viewer that looks and see and your trying to please them.
