As usual, I love the colouring and the linework. Though, as Sakura mentioned... the ginormous boobs are beginning to be a bit... much.
Anywho, been wondering something about your colouring technique... To get the colours that smooth, do you happen to use a coloured pencil blender? I had bought such a blender a while back but haven't used it yet. Or is the smoothness from the type of coloured pencil? Or even the type of paper? I've often wondered if watercolour pencils were used, as the background blending reminds me of that.
Hrm... I don't suppose if sometime you could put together a tutorial of sorts? Or at least a series of "in-progress" images to get a general idea of the colouring process used? I'd like to employ some of the techniques in my digital painting.
