The chicken design is cute, but try to bring a story to it. Let some chicken do something funny.
Also like Kott said, the square they are placed in is not good. Try to make it more dynamic!
Love to see the next version!
The love part is that only one chicken is facing the 'wrong' way and is kissing the chicken next to it. As a few have said, the white shirt isn't helping with showing any detail.
