Good selection of styles and images you've got going on there - you might find more specific crit posting them in the relevant section, however, I'll give you my thoughts...
Figures, very striking, especially the eyes. Like the use of photoshop, nice effects, realistic, and not to overdone. The two photos with the horizon in could be doing with being levelled out though, first thing I noticed.
There's obviously a lot of thought gone into these images, looking forward to seeing more...
