The first 3 portraits in your people section are very over processed in terms of skin smoothing – the second one especially looks very plasticy.
My favourite image you have in from your ‘things’ section, the fourth down, man directing a helicopter – it’s a great composition! I think entitling the section ‘things’ though, makes it sound like a place you have just put all your miscellaneous images without much thought. Most of them are military so I would take the rest out and have a more appropriate title.
I agree with eyedoc, only post your absolute best. Good luck!
