Hi Grahame , super images
I don't know why everybody likes only #2 but I like them both.
IMO rocks are a bit too much in the FG in #1, so I would crop to the end of the little curve on the lower right side. I loved the colours .
I like the composition in #2 as it is . I would actually make the colours look stronger and more vibrant but it is just personal preference. I'm reading a book about landscape photography and the author has very very colouful images in the book. I also watch some videos about landscape photography and filters from time to time and people try to make the colours really vibrant and strong in those videos. May be I'm impressed by those images and that's why I find the colours in #2 a bit pale
