I do see some elements of the clouds, particularly towards the top of the cloud, that are screaming "billboard" to me. Very detectable. The backside of clouds in shadow still have that solid smokey appearance that has plagued clouds of any sort in XP10 from the beginning. That's going to be a hard thing to overcome, I think. I do think this is an incredibly lovely system, nonetheless. Just offering up my own small contribution to the cause....trying to be constructive.
