I think you have a nice start. I love your look, and your eyes
If there is anything I could say to help you improve your skills as a model, and your portfolio, it would be to work on emoting. I can only really see one set of emotion in your port.
Browse through models ports and lists with "emoting" as their titles, and try replicating those emotions in front of your mirror. Don't fake the emotions, for each emotion or set of emotion, try to find a thougt or an event you remember that brings you that emotion when you think about it, just like actors do.
Hope this helps
