First of all, this is great,
I wish I could do something even similar.
The ground is among the most photorealistic things I have seen in TG.
I like the clouds too, but they have a slightly painted look in my opinion. Maybe this is a case for Buzzzz´s photoshop-technique.
Last but not least this looks a lot like norway or iceland to me, so I would replace the plant by a dwarf birch or one of those round stonelike pillowy wosnames.
To say it again, the ground is great!!
Best Regards,
Jan
