Thanks. You know, I have never really timed myself to see how long it takes, although colored pencils are a slow medium and with the detail that I strive to get, it takes a while. I would guess a couple weeks for one like this and this size. And of course I have life to live in between.... you know housework, animal husbandry, etc......and I don't mind you asking at all. I m happy to help anyone interested in colored pencil art.
