How about tweaking the logo by removing "Specializing in" - may be a bit more cleaner without the extra words? Leaving only "Motorsport Photography" in the logo....
I like your earlier renditions of this logo over #41. I think the gray is a bit soft and doesn't have the impact as the black and white you posted previously.
Thanks for your #162 - I like your #39 better and #38 better....The grey color in the G makes the design pop less to the viewer. The contrast of the true black and white stands out in your previous designs.
