Holy sweet baby Jesus this took me so long to finish ;-;
Admittedly I would have had it done a couple days sooner, but I had birthdays and such to deal with.
This is probably one of the biggest pieces I've done in forever ugh.
Not even kidding. This pic was originally about 6000x5000 and I had to scale it down because SAI's memory load just couldn't hack me editing it at that size once I'd reached the background colouring. ;;orz

Regardless of all that though, I really really enjoyed doing this one, and it also gave me a chance to try out techniques I haven't before!
I still have a long way to go when it comes to backgrounds.

Enjoy!
