That first revision is definitely an improvement, but I think you could still emphasize the visual hierarchy a little more. I know your character doesn't have outlines, but you could experiment with some outlining on the foreground layers to bring those out more. Also, The colors of all the elements are still very similar, and I know green is a particularly hard color to work with, but maybe try using relative color to suggest green rather then choosing a distinctly green hue for everything. As things recede into the background, the saturation and contrast should decrease, as well as the level of detail and shading that is necessary. Try integrating a teal tint, similar to the sky, into the rest of the background elements to group them together visually.

Yeah, the more I see the run cycle the more I find that 6 frames was a bit cheap. It's one of the animations the player will see the most, let's not make economies on it ! New version with 8 frames, feels way more inertial. also, jumps a bit higher durring the cycle.

New 8 frames :

Old 6 frames :

Definitely an improvement, I love it.

I don't have a problem with the warm colored highlights, as street lamps often cast an orange hue on things at night. I think making the light from the lamp more orange would help in portraying this.

As others have said, the visual hierarchy does seem a little unbalanced. You actually don't have that much detail in the background, so I think shifting the background elements to a much more limited palette would really improve the readability. Something like this:

Nice animations on the dwarf character; they have a good sense of weight and gravity. One thing that bugs me is that his legs seem a bit stiff on the run cycle- I think it might help if his knees bent a little more. Otherwise, good work.
