Hail countryman :) How are things?
About your last one, you'll do it monochromatic? or perhaps try some more tones there? that morning sun is really asking for some color :) The rest is looking nice and "moody"
Maybe later on add some birds flying near the "city", they fit a scenario such as this i think, and maybe some green bits on the rocky wall, near the watter...don't know, just my two cents..
Keep at it :)

Made weak by time and fate, but strong in will
to strive, to seek, to find, and not to yield." Lord Tennyson
