The picture doesn’t look sharp. The colours are nice but I don’t think they are enough for the whole picture. Maybe if you try and crop out some of the sky. The image is just missing something that will grab your eye and make you want to look at the picture. I know there’s not much up on them mountains but I think there’s an old cairn (or somethoing) up the top of one of the hills there (if memory serves) and maybe if you returned you could try getting a pic of that and incorpating the colours with that picture.
Sorry I can’t be much help. Maybe one of the more experienced people here could offer some better suggestions.
