God that is one happy chicken, especially considering it's just a head.
I just wanted to get in on the trend and show everyone how I draw step by step. This is a caricature of one of my pet chickens (which is actually a cuckoo color, but I got real lazy with the coloring).
Personally I quite like this style. It's loose and simple and reminds me of Looney Tunes. However I would have liked to have added irises (the colored bit around the pupil).
