Dandelion pattern

So this is for graphic design. We had to draw 120 little images and pick three and then make various patterns out of those three little drawings. I'm not really comfortable with patterns but this one was made a bit further down the line of the assignment. My teacher gave me this advice of making a little pattern or entirely new object out of the original three objects and using that to create a pattern, patternception. So I made this dandelion like thing. I'm pretty okay with this one. It makes me feel peaceful

Please view full size cause it looks oddly grainy if you don't.

So yeah...
ANY criticism... gimme cause I love critisism and I don't know what I'm doing with this. so tell me.
