This is a scene I put together for the IRTC several years ago and was never 
really thrilled with how it looked. Been attempting to convert it to a mcpov 
scene off and on for several weeks, which has proven difficult with how many 
different textures and objects involved. This is the result of about 17 
hours rendering. While it looks quite a bit better than the original I am 
still not really happy with it. The biggest challenge has been getting the 
textures to look the same. The bottom of the smaller tower should be about 
the same color as the rest but as you can see it is quite a bit lighter.

I'm very confused by the lighting and shadows.  That looks like the moon in 
the sky at night, but then there seems to be a big light source behind the 
camera somewhere.

Was trying to make it look like it was sunrise but may have ruined it by 
lightening the image in photoshop. This is the original image without any 
post-processing, not that it is any better. The moon is just a glow object 
so it doesn't show any phase.

This part of the scene is very good (the whole scene, in truth): it seems an old
photography.
"Bella" scene!

Ah ok, so the shadows from the trees are due to the sun? That makes more 
sense as I think it was the shadows of the leaves on the front building that 
was confusing me.  Very good modelling and textures though!

If it's supposed to be a full moon, then the sun would be behind the camera, 
not as it looks here, where I think it's high and to the right.

Also, at full moon, generally the moon is setting at sunrise.

The lighter base of the small tower looks very convincing to me. In fact, it's 
the base of the large tower that look to dark.

The lighting and the sky are more troubling.
If the sun is just raising behing you, it should be lower, same for the moon. 
Also, the sky near the horizon, under the moon, should be much darker, the 
bright part is behind you. With the sun "on" the horizon, it's light should have 
a redish cast.
