I find the text and the masking/outlining around the text to be a bit sharp compared to the rest. (unlike many others I have no problem with the red text and i think it actually works nicely in this context). It might be worth considering feathering/blurring just a tad to make it consistent with the drawn elements.

that having been said, i really like it. Please tell me you used the forest generator and didn't place all those trees individually

if you wanted to go really nuts (it's tedious but well worth the effort) there are a few spots on some rivers where the trees cut off halfway through (it is subtle but once you see it you can't unsee it lol). masking the river when it flows behind/under the trees can really help with the illusion of depth too. Hard to explain, i can point you to some examples if you don't follow.
