Not too bad... it's an improvement though.
GOOD:
A decent amount of trees. Not too many, not too little... pretty much just right! The backround hills and trees keeps the shot from being boring and stuck on one little isle with a waterfall
Sky also went well IMO with the shot because of the water...[Last picture]
BAD:
Terrain Variation isn't great; Should've added grass or grassy-dirt near trees. Waterfall can definatley be improved by adding maybe rocks at the bottom or maybe even coming out of it. The fact that the water from the waterfall is coming out of nowhere isn't too cool looking either. Fog is bad. I'd suggest light-blue or maybe dark-blue, something around there. The trees in the background should've been smaller to make it look like the hills are miles away and make them smaller and compact together making the hills look like they're covered in forests. The river rushes don't blend at all with the waterfall or the terrain either.
Not much to show really. Maybe add more than a couple islands and a waterfall?
Overall: 4.5/10
