You said be brutal so I'm going to be....
Well your site is BRUTALLY slow, please for the love of god don't use wix. WIX's interface is brutal. Max 5mpg file size? WFT?
Here's a bunch of other sites you should check out that are all 500000000x times better.
(What I use, link in sig, $50 a year but you don't get much customization)
Heck, even Tumblr is better than WIX and you can use your own domain for free.
I don't love your gallery layout, I think that as a client seeing all those images is a bit overwhelming, I really prefer a single image slideshow. I think your layout is very very very very very very very very very busy, keep it clean and simple, some of the best photographers lose out on clients because they have a poor website, go look at any sucesful photographer's site and 95% of the time it will be white/black/one-colour, and super simple and easy to navigate.
Only pick your best photos, if a image is just there for filler or to bulk up your site it shouldn't be there. If you don't have enough work to fill a category well, hold off till you do. EG, your entire snow category, why there are photos of a dog and go-pro screen shots is beyond me... Your entire lifestyle category is random snapshots, photos of money, springs, etc are not that exciting. Get rid of the equipment section, it doesn't matter what gear you have, what matters to the client is that you know how to use it and can use it well. Get rid of the links to your facebook, vimeo, etc. You don't want the client to see your sub par work, just your best stuff on your site. You can run a blog to update more frequently, but make sure the photos are still up to par. Also, there is a snowboard photo in the rock climbing section, might want to fix that.
I can't figure out what type of clients your trying to get? Getting hired as an action sports photographer is VERY hard and most of the time if you do it won't be for pay or you'll get a free t-shirt or other free merch.
Overall I'd say a good 75% of those photos aren't spectacular and don't really have a place other than filler. Maybe hold off on the website till you have a solid body of work.... Back last spring, I tried to build a site on WIX a while ago, and Michelle convinced me to wait till I had better images, really glad I did because now people know me for my current work, and not for my old, sub-par work.
Hope all that helps, as always feel free to PM me if you have any other questions,
