When it will be finished?
Best guess would be "when it is done".
You don't want to apply pressure when someone's doing artwork for you for free. Coyote probably has things going on that take precedence over this free sprite - they are doing this for experience and because of the challenge rather than any obligation to complete it for you.
Work on other areas of your game in the mean time and use the semi-completed sprite while it is being worked on. If Coyote is unable to finish the sprite, then I'm sure they'll allow a second artist to contribute towards its completion.
