Welcome to the forum David.
I had a look at your posted image and it is very sharp.
Like the others say 24MP is a good as anyone needs for portraits IMHO.
Any more and you need to soften images as very few people have perfect skin.
I would say that if you want to concentrate on your portrait photos then you have all the lenses you need. The 105mm f1.4 AFS is I am sure a very good lens but in terms of depth of field (DOF) it will be similar to the 85 f1.4 on a FX body. I talking practical use not theoretical calculations.
The FX v DX debate is one that will rage on like the old 36mm v 120 one used to so I wont go there.
In your case I would say you are equally well served for portraiture but there may be some very small advantage in a FX camera but in exchange you have a bigger and usually slightly heavier body.
It's fair to say that the performance difference between similar priced FX and DX bodies is now very small. As they say in motor racing circles..."it's the nut that holds the wheel that's the most important component".
