Green and Yellow Sketch

A little sketch I did of both Green and Yellow when I was coming up with the concept and design for Green's brother.  I had first wanted to make his hat made out of leaves or something, but then it suddenly hit me to make it a sunflower, it looks both super ridiculous, but super cute at the same time!  

Here I drew them in two different poses to show off their different personalities and characteristics, Green (on the left) is a lot more daring and mischievous and also quite the leader type, whilst Yellow (on the right) is a lot more on the shy side, he's a much bigger follower than he is a leader, but his smile shows that he's not ALL that reluctant to play any tricks, if anything, he plays just as many as his sister.
