Do you need art for a Mecha Kaiju Sensō Tai!!! campaign? There's a lot of awesome kaiju art on the internet that suits the bill, and an awful lot of it is by Matt Frank. While there's some awesome stuff on his professional page, his deviantART page has some absolutely pefect pieces for use as figure flats or flavor illustrations. If I ever get around to trying to produce a book of this setting (or if somebody with deeper pockets pays me for it), Matt Frank is my first choice of artist.
The following are from his Godzilla Neo project that reimagines characters from every era of Godzilla (including the cartoons). They'd take a bit of work to turn into custom figure flats, but they'd be worth it.
|Godzilla Jr (AKA Minya, Minilla)|
|Kiryu (Millenium Mechagodzilla)|
There's plenty more of both Godzilla series characters and crazier critters for the upcoming Colossal Kaiju Combat game at devaintART.
