@lordnick5000 - I made them. They're an edit of the larger RTP tree.
@LightAndMagic - I said I hate it when people overuse them, use ugly effects, or use them to hide bad mapping. Since this map, when finished, is for the opening sequence in my game, it needs extra impact.
The panorama is a placeholder for now, I'm working on my own. The RTP mountain one doesn't show enough blue sky, and I don't really like how it looks with the tiles, anyway.
