Love that widefield Marc. Honestly, I think there's not enough of it at this particular field of view, showing things in their context but still showing enough detail - nice!
Would definitely like to see more from this setup.
You have got some additional detail in your highlights that you could maybe tease out without going all HDR-crazy, if you feel it would add to the image ofcourse... (see attached for a one-click example).
Cheers,
