The whole idea was for a coffee sleeve (project for school) we were given three names of coffee flavours to choose from and free reign to illustrate it. Mine was bluesky coffee...(other options were jet fuel and redeye).
In my own criticism I'd say I should have knocked back the front blue bird and allowed more of the "flock" to show that's behind it, the concept was to have a flock of bluebirds turning the sky blue just with there numbers, but I think I got a little obsessive with the front bird...heh...
photo reference for the bird in the front (was originally hand sketched then scanned in), photoshop was used for the entire piece. The background was originally a chalk pastel sunset and the birds in the background are a mixture of photoshop/chalkpastel.
