Thanks, guys.
Oshyan, I'll gather the scenes and see, how big the files are, OK?
Btw, there are some things that won't be too noticeable in this low quality: the trees are animated in the first two scenes, which works quite well. Unfortunately the tree trunks are wobbling as well, but since the sun beams (hopefully) catches the eye, it won't be too obvious.
@Dorianvan: no, the fire is in the scene. Actually it is no fire at all, but just an orange light source and a small localised cloud layer with an animated cloud fractal.
