You have a good portfolio. And I notice that some images have an HDR look about them, like the three cyclists shot. Not necessarily bad, it just depends on your market and clients and what you intend to convey. Regarding these images, I think they work as a series that intends to show how certain manoeuvers are done, but they do not have the same dynamic quality as many in your portfolio. No question, the backgrounds are intrusive, but fine if the aim is simply to convey dramatic manoeuvers. I might add, I find the colour shirt image somewhat distracting. Looks much better in BW, as does the whole the series. BW seems to focus attention on the manouevers while minimizing the background.
