I don't generally click on links to view peoples pictures, but given the quick and visceral reaction to this post, I decided to take a look.
Your portraits need a lot of work. i noticed on most of them you have very harsh shadowing and need fill flash, or more even lighting conditions, the exposure on most of them is poor. there are a lot of highlights blown out, and the composition seems a bit haphazard on many of them, like they are just random snapshots of people wherever they just happened to be. Your wildlife shots appeared to be much better than your people shots, and I saw much better lighting in that area.
Iphone shots? not sure what the market is for that on a page you wish to market on a professional level. but if you can sell them, go for it.
definitely get a better "about me" picture taken. the one you have appears to be an Iphone self portrait with harsh flash lighting, and you are far too pretty to be represented as a professional (or at all) by such a poor photo. your landscape section seemed a little bland, like they were just random shots of places with very few actually catching my attention, but again, they were better exposed than your people portraits. the Yosemite shots were much more compelling to me, and seemed well exposed, and well picked locations. I didn't care much for the flower shots, but thats just my personal taste. I didn't see much in the way of focus issues, so that's a good start.
