Classic Sal Buscema Hulk reproduction

This past week, I've been getting back into sketching a little. I've been using a brilliant iPad app called ProCreate, and this is what I came up with the other day:

Original by Sal Buscema, digital inks & colours
by Simon Williams using ProCreate for iPad

The program allowed me to import Sal's original image, and then ink and colour it on separate layers.. like in Photoshop. I then deleted Sal's original layer... and viola! A Soulman Inc reproduction of the first ever image I ever saw of the big Green guy (from which I became a fan for life!)! 

Hope you all like it!
