Hi Martưn,
welcome to CiC, it's nice to have you on board.
I can see why you like this picture; it's got an feeling of mystery to it.
If you don’t mind me saying I think the ‘blown’ out sky between the trees needs to be darken using the ‘Burn’ tool in PP. It is extremely un-likely that you will be able to pull any detail out of that area, as I think it is lost, but if you can make it a bit less obvious I think that would help.
I would also adjust the contrast a bit to give the picture a feeling of depth and some sharpening in PP.
The other members with more experience will certainly offer you more constructive advice if you need it.
Thank you for sharing your work and I look forward to seeing more of it soon.
