I agree, for a portfolio you probably don't need that many photos and probably want to pick your best. I think it's a matter of trying to look at your photos objectively and to differentiate between ones that you might like for a particular reason, and those that are the best.
The street photography section to me isn't the strongest because of so many that seem washed out or underexposed (or were edited to look that way?); I realize a lot of people seem to like that look but these seem to not be the best quality overall. But there are some that are interesting that might possibly be included as portraits - the man in the reddish tall hat/scarf (although I find the people in the background distracting, I'd try waiting a split second til they move into positions that fit better in your shot), 'Brun' Food Store reflection, they guy next to the statue (altho he isn't looking like he's real sure about being in your picture).
Some of the portraits that are interesting to me are the girl on the different color benches, the pool player in B&W and Thrive. The thing I'd think about are little distractions, the black shape near the guy's sleeve, the part of the white ID at the bottom of his lanyard (an easy crop) - I find my eye goes to those shapes and they're distractions because I find myself wondering what it is. Some of the B&W portraits to me seem grays more than black and white but Thrive is pretty cool and something different.
Your photos of the Smokies are very nice, I love the road and fence in the fog. Those are something different than what you typically see of the Smokies (I haven't been there in years and your pictures make me want to go back). Some of your photos are unique and those are the ones I'd think about showcasing on your site since they seem to stand out. I think some editing would be all you need as you obviously have talent.
