as I just promissed, here is the gooood stuff, I've been playing a lot with the "Finger" tool on photoshop to makes my shadows much faster, what do you think ? I'm personally very pleased with the result, and Dozy is too ;3
(just so you know I used to do shadow this way: I placed them, then sculpted them with the rubber tool, it took a lot of time and hundreds of layers, but by using the finger tool, 1 to 3 layers are more than enough !)
anyway, I hope you like it !
