This seems a bit soft and seems lacking in the kind of crisp detail that I expect an image of such a subject to have. Maybe stopping down the lens to a smaller aperture and using a longer exposure? Not sure.
I think the lighting could have been better for this photo. The photo also does not appear sharp. For these simple photos to work, they need to be very sharp, and the lighting needs to make it stand out
Color spectrum is pretty neat, but the image is a little dark and the focus is a bit soft. I'd love to see this photo lightened up, I think it could really pop!
