Thanks for putting this up. If its not too much to ask could you give us some insight on what you did in each step. I'm curious as to why you decided change from a green hue to a more earth tone on the 6th panel?
this was a single-sitting pic for the most part and nothing really special as it was more character concept than anything. one layer for the most part and one brush. the colour change happens. i save it one way, don't like it, change it later. i do that with levels (control+M)
