I love this shot it is really something quite special an amazing sky and lovely firey colours.
I don't really know what to suggest to improve it as I love it as is, the only thing personally with me being from Devon is maybe you could clone the bits of Cornwall out
Only Joking it is a great county and has a stunning coastline my wife lived in Cornwall for 20 years so I spent a lot of time with her there until she eventually move in with me.
I digress great shot and one to be really proud of great work.
