How to draw wings - resources

first of all, please forgive me my crappy inking, my hands are shaky...and that some of the wings are smaller that the others

I post it here because I'm a huge wing freak and that a LOT of people have trouble drawing feathered wings, even the great artists - my eyes are bleeding seeing the pictures of angels, gryphons, pegasus or so on with absolutely stunning anatomy, great use of colours and BANG! bad wings (did I mention that I'm a huge wing freak? )

it's not really a tutorial, it's more like a reference sheet or resource. I know it from my own experience that to find a good reference for feathered wings is pretty hard and I doubt many people have the patience to study pigeons on their bus stop. I was lucky because my art teacher brought us few months ago a beautiful (and ooooold) book with animal anatomy (from horses, dogs, bats to birds or fishes). so I copied the wings (by hand) from that book because it was a great source. so don't give me the credit, I only put it together and post it here for your use. I only hope it will help you (cuz it did help me a lot)

sooooo my parting words are - have fun with your wings
