Here's some basic starter material. Beach Houses, fountains, statues, buildings, office furniture and anything that's possibly copyrighted or trademarked, are all out.

Good Luck.

istock take pictures right out of the camera with a mild postprocessing.

Shutterstock wants POP.
Your pictures lack pop and worse, they are not presice on the keywords or concepts.

You will get the "property release" rejection on many, LCV on others and bad lighting on the rest.
The beachouses might pass.

Sorry. To say...

BTW, I get a lot of overfiltered rejections from istock, when I upload my popped up shutterstock pictures to them.

Well...I was going to rate my favorite photos using IS's rating system and then let you know, but..............................like so many other things on IS, the ratings system isn't working properly.   

Just rated one, no problem for me.

Just to be clear, I wasn't asking for a comparison between SS and IS, I was just asking for which photos of my I should put forward to SS, maybe on their forum, for further critique.

Thanks for those who's taken time to review the portfolio.

Most of your photos, if sharp, will be digned for uneven lighting. A lot of them if not all.  SS does not like shadows. Your food shots will not pass for example. A shadow from the dish overcasting the sauce, no go. Etc etc. You have a lot of blown out skies. And you need a PR for 70% of your portfolio. I like your beach house shots, they are your best imho. The one that could work at SS is your wooden boat photo. Love that one too. I Like your landscapes but they are taken at the wrong time of day with hard  light and missing some clouds.

I suggest posting in the critique forum at SS, the peeps over there might be harsh in their critique but honest and they will work with you until you get accepted, no matter how long it takes.

My two eurocents.
