I'm new to modeling, and just need some input on my portfolio,  thanks.

I'd say keep all the Radiant shots and ditch the rest. You have a great look and wide range, which Radiant has shown nicely. In terms of your avatar, choose the one that shows you doing the kind of shoot you want to do more of. If that's the one you have now, then great. If not, choose another. Best of luck!
