Modelling: Elbow

I want to give my characer an elbow so that when it comes to skinning the character (hopefully) it should be easier to make the asrm deform the way I wish to, also making the crease in between the forearm and the upper arm will hopefully help.

To make the elbow I just gradually added in more edges and pulled out the vertices according to how I wanted the elbow shape to be, I found from this that I also needed to add more edges to the rest of the arm to maintain a decent shape for the arm.

This is the smoothed image, but not how the final look of the elbow is:
