i found no fault with the breasts and their shaping. the artist just likes em big, and there's a limit to how realistic you can make that size look. it doesn't really affect the art negatively. in fact i would say saburou is definitely one of the better artists out there for big chested women.
didn't mind the nipples too, aren't that kind common in hentai anyway? i thought you guys were too picky there -.-"
