I guess in a way it is an hdr to some affect but I do it differently than the standard 3 image stack up if you will.is this a HDR image? I am looking at the HALO effect behind the mountain range.
Unfortunately when you did the "layer stack up" it made some parts of the photo look like they were cut & pasted in. Like when the rocks of the bottom left meet the water, that looks kind of weird.
I think instead you should try a subtle hdr.
Just my 2 cents.
