I think there is a lot going on in your portfolio. Its very hard for me to focus and actually look at your photos. That is from a visual stand point for me personally. Its overwhelming. I do not think you need to have all of those photos in your portfolio to show your skill. You could get rid of over half of the pictures and be perfectly fine.
I think now you need to figure out what sort of modeling you would like to pursue. Fashion? Commercial? Art? Then figure out how to sell yourself in the market you choose to be in.
Also work on the small details. You are very good at posing but remember long neck, relax your hands and more intensity in the eyes.
Here are the photos I think you should get rid of:
You look bored/dead in this photo. No good.
No neck in this photo.
No intensity in the eyes.
Doesn't really show your modeling capabilities.
Here are the ones that you should keep. In fact I think you would be fine just having these in your portfolio.
