I wouldn't put this there unless you want it to be ignored by 90% of the board. Generally most of us just go in there on random chances because of what the board is full of.
I wouldn't mind seeing some of your freelance work, because what you have on your site doesn't appear to reflect the quality of the head model you've been showing off.
It is a bad practise to keep a portfolio so lapse, as if I were a prospective employeer I'd want to see what your capable of right now.
While your modelling style is relatively good, the head does seem a little polygon rich around the facial features, yet bland in other areas. You want to try to keep the flow of the mesh, and make up for any polygon depth loss with the texture and shading.
While a good Bake can help this, never forget that you can always create a basic model then using something like Texporter create a higher polygon one to give your bakes a normalised feel to them..
I wouldn't mind seeing some better peices beside just the head
