It looks good so far...

I think it needs more detail such as window fittings (HL2 models from multiple maps) and the doorways etc.

Also the tree foliage stuff looks a bit thick. Might I suggest the thinner leaf coverage and that the trees have some brown leaves on them? The light environment and sky don't fit with each other either. The sky suggests a much bluer light. Try making a 3D skybox for it too.

I think Orphs comments may be a slight exaggeration to some degree also...

All I can say now (until I catch my breath) is "Oh My!"

I may definitely have to download this one.

From the screens alone, this proves that 90* angles still work. :smile:

/me lets you know what I thought, later.
