Cheers guys, this is good, actionable feedback
If I'd had something longer than 23 with me I would tried something with compression, this was shot at 16 and I think it might have been better at 23 or 35 trying to use the rocks to frame and the stream to lead the eye to the island.
The light was flat and uninspiring so I'm planning on going back and repeating on a nicer evening, I need to improve my meteorology/planning skills I think!
Yeah I'm getting my head back around new lightroom and have just discovered masking for ND grads and I think that might help. I think you're right on the lack of contrast, I might try adding some and re editing.
