Very nice Roger!  I think you can up the brightness a bit but great framing! 👍

This is probably your best image so far. Although I should say "images" as it is a 4 panel mosaic.  I agree with Roberto though that it is a little on the dark side. 

Great effort.

Brighter version is better.

Really nice Roger, the brighter one shows more dynamic range but the darker one has a brooding presence to it. Good take on an old favourite  :D

Nice Image Roger. Agree with the others, brighter version is more impactful.
