Touhou- Subterranean Rest

So I'm being experimental again. Using Water Colours mainly.
I originally was only going to draw Utsuho, but then I decided to draw all four of the residents of the Palace of the Earth's Spirits: Satori, Rin (Orin), Utsuho (Okuu) and Koishi.
Now I feel like I drew this picture slightly odd at points. For example, the girls' legs mostly spread open instead of closed together, but hey, it's not like girls have to sit like that anyway. Though I was also inspired by one of the Kingdom Hearts: Final Mix artworks, and by the original Pokemon artwork.
Other screw ups, are like Utsuho facing to Koishi even though she can't so easily be noticed... which makes me wonder, if say Lucario closed his eyes to use his Aura to see his surroundings (like he did in his own movie), would he just not see her?
I don't know, but I'm getting off track now.

The residents of the Palace of the Earth's Spirits all belong to Team Shanghai Alice/ZUN
This art piece belongs to me.

[UPDATE]
Added a ZIP file in the purchase section where you can download the picture above without the signature of mine (if that bothers you) and the original PSD file.
The normal PNG can still be downloaded for free though.
