So I'm looking at your portfolio with a critical eye and trying to decide what to remove. If your plan is to get a job placement I wouldn't say any of your pieces are portfolio worthy, you've got a bit to go until you hit that quality bar. Do you have any ZBrush sculpts which are anatomy studies? I would suggest focusing on doing some awesome anatomy sculpts right now.
I'm with Ashervisalis on this. Your anatomy is low quality at the moment. The above suggestion to develop that aspect of your skillset is sound I think. Also more accurate and expressive material representation. You might try using Daz3D as a reference while practicing sculpting figures. Daz3D is free to use.
