Very well done!
You can dead straight see that this was done via ink and water colours, my favorite combination :>
The colours are very nicely composed together, but the sky seems just not to fit there. (Unless it's somehow relative to the show) more regularly placed clouds would seem to fit up.
Anyway good job ;)
I tried to replicate the clouds in the screen shot I was using as a reference but maybe the water colours don't give it justice.
