Number 1 looks excellent. It really looks like a HUGE crater, whereas number 2 looks like the craters could be any size (could be a few feet across).
With number 1 I see it as an enormous crater and all the different levels down the inside wall like a giant open-cut mine. And the hill in the centre actually looks like an enormous mini-mountain!!!
Strange how some things look big and others look small.
Wow these look amazing on my CRT Mike, great work.
I was about to write the same thing, just as I noticed Ken's post.
Moretus does looks like an open-cut mine, fantastic mate.
