I love your snowman, Quilte. you have button eyes not coal as we do here. The blue in the tie and hat band blend in with the scene, no 'pop' factor or contrast. No white needed in the eyes. Maybe a broom handle out each side for arms, one up and one down, with mittens on the end of each length on each side...more chances for color, along with three buttons down the belly.
Just my 2 cents worth of suggestions, but I think the 'snowman' is Ok; could be a snowlady with a bonnet on her head, flowering scarf, red mouth, 'wig' on her head, colorful buttons down the middle or an apron on her lower middle,, lipstick on her face...you get the picture...or just a skier with ski poles on the side with 'stick' hands and mittens, etc. A cowboy with a ten gallon hat...a baker with a chef's hat...
Yep, imagination is great....doing it is another. Add more contrast to what you have would work...just fine.
