hey ! I'm glad you like it Actually, I don't really have any workflow for the passage from grayscale to color. A lot of experimenting with layer modes untill I get the fealing that it goes in the right direction But for this one, I remember that I did some lynx studies before I started the concept.
Hey Well, overall, drawing on a tablet is pretty much the same than on paper. You just need to get used to the eye-hand coordination wich is slightly different as the drawing will appear on the screen and not on the tablet. This is probably the main difference between digital and traditional drawing. Allthough, there are tablets ( like Cintiq ) wich are like some kind of screen/computer integrated that allows you to draw directly on your painting but I havn't tried them.
Obviously, the feeling and the touch will be different. Not even speaking of all the key shortcuts etc ( especially ctrl-Z ) that, once you get used to them, are definitely missing when you get back to traditional pencil. But both are really just tools, it just a matter of practice I guess and personal preference
