Agreed! That’s a big improvement. Hopefully you keep on developing it.
A few more things to consider:
If brown is your prevalent color, perhaps introduce a variety of browns like Lunatique mentioned. Slightly cooler temperature or grayed down browns in the background and richer or warmer browns for the foreground skeleton.
I wouldn’t start the rope at the very corner of the frame. It has the effect of dividing the canvas in half. You may want to experiment with the placement. Such as moving it a little to the right or a little to the top.
Also, the canvas size seems to be of equal proportions. Rectangles are more attractive, which would be great for this canyon landscape.
The rope seems to be of equal width from start to finish. Perhaps reduce it in size as it stretches out towards the second skeleton.
These are just some thoughts. Anyhow, great update!
