It’t not finished yet and might be changed completely, but here’s a peek. Inspired by a 1931 lobby card and a poster of Frankenstein the movie, I think it fits perfectly. Take a look. Franky is redrawn in Japanese Super Deformed style. Everything is made with Adobe Photoshop, converted with Vector Magic and then imported in Adobe Illustrator. This version took about 10 hours.

I am no friend of japanese manga, but otherwise it´s a nice box art picture. 🙂 It´s a good idea to use Frankenstein picture to Franky product! 🙂
