Here's a few random images I made using MikuMikuDance and Montecore's/Predator's model of a busty Chirno.
I tried model some of the poses based on real people. So far I've only done 2 :P

I used these tools or mods:

MikuMikuDance English: http://www.geocities.jp/higuchuu4/index_e.htm (the d/l link under section 1.3 is the latest version).
PMDEditor: https://sites.google.com/site/mikumikubeat/tutorials/pmdedit
Chirno model: http://www.dlsite.com/maniax/work/=/product_id/RJ117312.html
Various items and stages from deviantart (under no permissions).

If anyone knows more naked models that are up for download (or buy like this one), please do make a comment below.

Note: Considering the model is hi-res, the images are also mostly high-res. 1920x2160 to be exact.

For anyone who votes on the tags, it is not Rei from NGE. I thought so from the beginning, but it's definitly C(h)irno from Touhou Project

Base +11, Dimitro -9

I'm pretty sure the Cirno model is a modified Rei model (given the hairstyle and the body type), but yeah, this is (intended) to be Cirno. A made-from-scratch Cirno would probably be a bit more petite.

Base +24, Kitsune Nishidate +11, Dimitro +9, ms_dos1 +6
