Nice Lee! Its certainly a good choice for the zone system!! I have not seen the version changes on this one, but I find the clouds and the dome nicely processed.

I liked your other version better Lee..... This is just washed out. Perhaps you could simply overly with a layer on the clouds to make them stand out a bit more, but honestly I liked your original version :)
This is really cool, Lee. What a fascinating image! The composition is wonderful... add in all of those shapes with the puffy clouds... brilliant.
