1) The color scheme is gorgeous and really helps to set the overall mood.
2) You have a developed understanding of focal points, and I found myself instantly drawn to the main character of the scene. Your scene is well deigned to pull our eyes to that woman just standing at the edge of this creek. Overall nothing is fighting for my attention too much.
3) you left 2 spots for my eyes to rest (which is great in the art world) one being the bottom right reflection and the other being the moons in the sky.
4) There is not a spot in this piece where it's not just awe-inspiring.
There are a few minor things that I notice when looking at the image:
1) The trees to our left seem to have some artifacting occurring on the trunks. Nothing noticeable from a zoomed out perspective but if you get any type of close it becomes quite apparent.
2) The suspended (I'm assuming) rail going through the trees seems to overlap some of the trunks and just seems to contrast against them too much (mainly on the right side of the image). Also the shadow cast by this doesn't diffuse at all. Typically a shadow becomes exceedingly more diffused the further away from the object your get, especially for the smaller top rail.
3) On the topic of shadows, everything seems to be casting a shadow except for your character. I'm not completely sure if this was done to make her pop or just an oversight or something else, but I thought I would bring it up here.
I love your image overall. It's one of the most impactful pieces I've seen in a long time! It tells a story and just pulls my attention right in. I found my self inspired and unable to look away at all, so great job! I hope you continue to produce amazing pieces like this
but it my first time seeing it ...
