Master Copy "sketch" of july

Cgtalk sketch is off for few weeks and I was looking for an topic. I see lots people saying that you should do atleast one master copy in a month. Trying to get as close as possible to the original painting. Currently I dont have so much time in a day because work and everything so I had only 1h time to finish this master copy. I was looking Cgtalk.com`s best works and I chose this really beautiful 3d art called "Atlantis Herald" by Alexey Kashpersky.
Here is the original

I had no time for coloring and because the timing was so strict I was only concentrating on general "flow" and values.
