HELP! Regen faces small

Hi all,

I am currently using Vitrex's skin at the following resolution due to the fact that I am playing the FM on a Macbook Pro with a retina display. However, the problem I am having is the regen faces are coming up small in the profile section, in comparison to the cut out faces of real players.

Would anyone know why this is the case? Is it because of the resolution? Also, is there a way of making the faces bigger?

Thanks for help in advance. Here are three screenshots to give you an idea of my problem...
