No tips, no help? Buuu:( 
This message didn’t show up until today…least for me. Sometimes there are delays…doesn’t mean no one is here to comment…just that we may not have seen it yet.
It’s not bad for a 1st zbrush model. One thing you might want to do as well is include a wire frame of it…that way folks can see how you went about it and it might offer up some more ideas to help you.
I maybe would have added stonehenge in the back ground since alot of folks associate stonehenge with druids.
Other than that…experiment and play…its the best part of zbrush…post some wips along the way, play and experiment, have some fun, check out the forum for tips and tricks people gladly share with us, watch the zscripts included with z2 and definitely if you haven’t done so…check out the practical guide…most of what you might want to learn about is in there and will take you step by step on the how to’s!!
