Im new to modeling, would love any advice you may have for my portfolio!

Welcome...not a bad start at least they show that rockin' body! Good luck!

Looks good! But I don't like any of the photographer's exposures, they were all overexposed, too grey, etc (but that is a different topic).

Try adding a few more full body pics, standing poses, preferably.

Also try having the light hit you from the side or corner instead of head on all the time.

Always have your pose go against the key light (primary light), and look towards the key light.

If you can, ask the photographer to use a longer lens, the short lens distorts your body/figure. You will need more room for that kind of pose of course.
