The Shadows in the Twilight

So, before I really start to explain anything with this picture, I'm going to apologize for the recent in-activity but It'll all be revealed soon as to what I've been doing.

Anyway, This drawing Is actually the first picture I've ever done in Paint tool Sai. I just got the trial download last week and I've been playing around with it. This really did just start out as a lazy sketch but turned into  this whole thing. 

I'll have to get the full version of Sai if work keeps going on like this!

Thanks for the views everyone!
