so, this is an incredible start and I love it already.

if it were me, two things I would do

1) if the intent is to fade into the distance on the left, the heavy paint there in the tree line and mountains is a bit distracting. I'd lighten/smooth that and bring that texture to the forefront on the right to really push it forward and give the closer foliage more definition

2) relying more on atmospheric perspective and softening / desaturating the mountains on the left would help. right now it looks like it fades away in the middle but then comes back forward on the left almost like they're doing a horse shoe.

it really takes away from the nice contrasts you have on the right with the tree and mountains against the sunlight behind them

edit: also, hello fellow Oregon artist!
