I don't have time to give a picture by picture opinion but 1-4 don't work with that style of mountain as they are to flat looking... 5-6 look GREAT! However they should be smaller to better show scale with the mountains and... 7-11 are a really nice look for this type of map but I think that the ones in 9 are what you are looking for as far as matching the mountains... (Although not my favorite)

As I see it the main problem here is that the "shading" on the trees needs to look good with (match) the shading on the mountains or maybe just have less as in 7. I like the look of 8 & 11 the best but you would need to “lighten” the shading on the mountains to match... in my opinion.

I like how the map is coming along and I look forward to your next update!
