Hello Mehdi,
You have a fine collection here, including a few that I really like, (especially the brief moment in Yosemite); however I find the layout and labeling a little off-kilter.
I would have preferred to see each image with the label instead of the camera data. Clients are probably not going to be interested in shutter speed and aperture, or time of capture. instead the title should lead the viewer to the image - not sure if I explained that well.
Also, I would be inclined to group them according to subject or theme.
I hope this helps. I notice that you are using the same internet provider as me and wondered whether you have used their gallery or some other?
Anyway congratulations on your great images.
Bob.
