I agree with Drew and Lee above.
Images should 'sell' you to photographers, so should only be the best. Your portfolio lets you down.
A few of comments to help you select: Water runs downhill, so in the background should be horizontal; try to use the 'rule of thirds' in images that you show, it is more pleasing to most to view (hardwired into our brains); try not to show almost identical images - it just dilutes the portfolio; try varying your expression - practice in front of a mirror; add a plain simple headshot so photographers can see you - your eyes should be razor sharp in it; be very careful of the cropping of your images - for the most part crops shouldn't cut joints (e.g., elbow) and need to be placed carefully not to distract.
Finally, although you asked about images I almost didn't get past your bio. Please don't use the third person, it doesn't read professionally. Rather, it gives the impression that you can't follow the guidelines for this site. If you can't follow such a simple instruction how could I, as a potential photographer, trust you would pose in the way I need?
None of the above should be seen as 'deal-breakers' to your modelling aspirations, just items to work on. Good luck.
