The HDR shots have a tendency to be 'overcooked'. The telltale sign of this is visible haloing around objects. It is very easy to over-tonemap HDR images because they look so dynamic. Unfortunately the eyes quickly tire and images can become simply garish looking. Try reducing the 'strength' (or whatever term is given in the program you process HDR images with) a bit to reduce the haloing. The result may not be as dynamic but the image may have more longevity. On the other hand if you like the image the way it is then that is all that matters.
The black and white images don't 'do it' for me, sorry, and not because I don't like black and white photography; I do. The images simply do not hold my interest.
Some of the interior/close up photos, on the other hand, I consider excellent and although based only on a tiny sample of images on the site, in my opinion your photographic strength lies in this area. Some of these images really 'pop' and for me would not look out of place in an official product brochure.
Not sure if you will consider my opinion "kind", but it is
honest.
Kind regards,
