Yatagarasu's arm cannon
A CG from Touhou Mecha ([link]), a fangame of Team Shanghai Alice's Touhou Project. It's a short, art-intensive Visual Novel drawn and written by me. More information and downloads for this fangame can be found at the DSD blog. [link]
This is Utsuho Reiuji's mech, known as the Yatagarasu. Basically, in Touhou Mecha many of the power-related traits and design quirks of the original Touhou Project characters have transferred over to the mecha. As the Touhou fans will recognize, the "control rod" on Utsuho's right arm is the basis for the AM Yatagarasu's arm cannon, pictured here. The red gem on the chest and the black wings are also features that have transferred over.
The native resolution of the game is 800 x 600, but some of the CGs such as this one pan, so it's a bit larger than that.
