In November, I bought an interesting-looking doujinshi called Bolt On by a mangaka named Ocha. While it is an original doujin manga, it also contains some great fan art too.
The Ingram from Patlabor.
Anice Farm from Sonic Soldier Borgman.
Priss from Bubblegum Crisis.
Sylvie from Bubblegum Crisis.
This doujinshi features original manga stories by Ocha and they feature rather nice artwork.
