I see your photo post has had many views and no comments from viewers.
I know that can be disappointing and often discourages people from posting/participating in a forum like this.
So, I will post a comment or two and maybe that will get others to contribute their views too.
As with anything where a subjective view (opinion) is shared, there can be many views of the same issue or subject.

I am posting a comment in your post because NO ONE else took the time to thank you for adding photos for us to view. I believe in "The Golden Rule" (treat others as you would like to be treated). It is "good karma" too.

Good job on the photos.
The "helmet visor up" photo reminds me of one I posted about 18 months ago of a young boy who is a race car driver.

What do I think would improve these shots?
I think more lights to define the forms would be nicer, especially on the bike and some top light on the Helmet Visor Up shot.
I think all are perfectly fine, love the duc, and its a flat black bike ^, so controlling light is a little tougher, i understand also great job cloning out the bell logo in 1, needed it. Have room to do any wider shots?
I do wish you got a shot of him on it visor down in a full tuck looking ahead setup like shot 3.
