Hey Massimo, This has some really nice textures and patterns working here. Good details. I would explore in a for some closer shots, you can see a lot of cool patterns and textures everywhere in this trunk.
I agree with Mike. As is there's nothing extremely interesting to pull the viewer's attention into the image but a bit closer in and you may have some amazing details to hit them with.
It does look like you got all the technicals right - nice capture and good lighting.
I think you're on to something here Massimo. And I like where you are headed. The textures and color makes for an interesting and appealing composition. It gotten me to start looking at tree bark a little differently! ;)
Thank you all for your comments--I have been playing around with this image (and others in the group) and will post other versions later. You are right: there are lots of possibilities here.
Glad to have drawn your attention to something we take for granted!
