Definitely dynamic, love it! I do have a few bits of feedback though if you're willing to change much. Firstly her balance is really off, when you consider the possibility of just how fast that rock creature is moving, she doesn't match it or even look like she's on the same plane as the bit of shoulder she's standing on. The actual form of the same arm doesn't fit completely into the perspective you've chosen to draw it into and this makes it look just a little flat! Your detailing is fantastic though, and the blue between the rocks leading to the ball of power is really well done, lots of variety in value and colour and it works well.
I personally think more could be done with the ball of power itself, incorporate more of the blue or give it some texture, it does look somewhat unfinished compared to the rest of the piece and for me lets it down a little. The clouds, dust and atmosphere over that forearm is really really well done however and works well.
Overall the piece is honestly so good but just needs a bit of tweaking to be amazing! Good job on it, you should be proud
