Narrative is one thing, framing is another.
What I love about this piece is that it has been framed to give a sense of the impressive scale of this giant creature - perhaps it could play on the scale a little more - although it's nice to see the artist taking framing seriously.
With that being said, you might be thinking that the frame is a little wide - it isn't. It's angled upwards for sense of scale, and it is wide so that you can see the ground, and can use the characters standing or walking in the sand under the creature just to emphasize the scale a little further.
What else makes this picture amazing is the use of compelling and photo-real textures in the sand, rocks, the creature's scales, and of course, the clouds.
