All of these backgrounds were created with a new(er) software i found from classmates called Alchemy, it's a vector based drawing program which lets you draw shapes and form very quickly.
I use it to get my shapes down before i go in and add color and light inside Photoshop.
I've been very inspiried by Pascal Campion recently with his work and thoughts, also i like Lou Romano's work quite a bit since i saw Incredibles.
The head sketches were created using Harmony ( not that software though haha ) it's a browser based drawing program i found that i love so much, such great texture and line
cheers~
