I really like your site, a lot! I like the fact that you write about your work and your method. Too many photographers put up pictures and then say some cliched thing like "my work speaks for itself." I like your goals and statistics. I like hearing about your journeys in the highlands.
But, I think you put too many pictures up to call it a portfolio, not just in your cloud gallery. You have some great stuff here mixed in with some good stuff and some pretty decent stuff. I think the great stuff gets lost in the large collection. If this were a travel log, the volume of photos might be more understandable, but as a photo portfolio, it is too much.
Sunrise/sunset is another great technique we use in photography. I like your clouds and sunrise photos. There are a couple extraordinary shots in there. There are a couple shots that are, more or less, duplicates of others. If you whittle them down a bit, I think they would be a stronger collection. I would also try to group similar shots together. It can be nice to see the color progression of the sky across three or four similarly framed shots.
So, my opinion is you need some judicious pruning then re-sequencing of the collection. The pure cloud studies (without any ocean or beach) are the best of the bunch, though.
