So for starters, this is an amazing piece. When it comes to showing the enormity of a scene, you're one of my favorite artists to portray it. That being said there are a couple things that I'd critique. The main one being the sense of depth of field. Because this is such a massive landscape (judging by the human scale vs. the tower in the distance), I'd expect there to be a little bit more atmospheric perspective to push back the distant cliffs, and the waterfalls' spray would justify a bit of mist to help push things back (I see that there is a bit behind the mid-ground waterfall). I know it's meant to be a darker scene with lights that come through to shine on a few pieces, but the contrast is just a bit lacking, and the darker shapes kind of bleed together. The waterfalls help pop things out, but it could use just a bit of tweaking. Again, this is hyper-critical, and overall I love this piece (and all your work really), just thought I'd throw in my two cents. Keep up the good work, my friend.
