The forward lean pose typically makes the head larger which if desired is ok. It appears that you're using cross lighting which I love, however may I suggest that you bring the lights forward just a bit more. I think you may find some results that could be pleasing. The best thing to do is experiment with the lights in different positions until you get the desired result. Really look at the light and shadows when setting the lights and composing the portrait. Every little detail makes a huge difference.
