All that is gold does not glitter, Not all those who wander are lost; The old that is strong does not wither, Deep roots are not reached by the frost. From the ashes a fire shall be woken, A light from the shadows shall spring; Renewed shall be blade that was broken, The crownless again shall be king. - JRR Tolkien (The Fellowship of the Ring)
Wow...render or photo? I honestly dunno. If it is a render, then I think you have done a lot of good post-photo work fixing the waterlines. If it is a photo, then I can't think where it was taken because the environment is so "clean"...no little piece of flotsam in it. OK, I'm guessing render. On to the pic itself...it is spooky...very evocative of a mood, almost other-worldly. I don't like the blast of slight in the center of the page...but that is my personal preference. Nice job.
Lovely colours and light. I'm not keen on the land texture, but I tend to have that reservation anyway. I like the feeling of space here and the hint of more distant mountains which look almost ghostly.
P.s. is this a terragen render or a real photo??
