You're really into that mid-tone contrast HDR style huh. Some pretty cool shots for sure, but I feel the processing sometimes becomes distracting and makes every image hit a similar note, If that makes sense. Interesting subject matter!
Great Images, I like your B&W in particular, seems to suit Africa so well.
I see your into the High Contrast work with spades, and in many Images this works well to create a particular impact especially where colour is concerned, my feel though is that it's perhaps a little overdone in todays Photographers, that is not to say it detracts from your images, just that many Photographers have gone down the "Trey Ratcliffe" path & continue to do nothing else, often I feel High Contrast works, but more often I feel it doesn't, I guess it depends on the Image.
