It does indeed look excellent. However the cliffs are not, in fact, vertical. The fact that the chalk is so soft (and thus increasing the gap between Britain and France at quite a rate!) means that there are always chunks missing in various places. I'm not referring to a few metres square, either. I was watching a TV programme a short while ago discussing the chalk cliffs and that during a storm, it's not unusual for hundreds of cubic metres of chalk to fall away in uneven chunks.
What you've done there looks pretty close to what they were showing in close up shots... Except without the green bleed from the textures, obviously. :d
