Layer Cake Quilt Along - Blocks Six, Eleven & Twelve

I'm finished/caught up on the Layer Cake Quilt Along. And... I don't think I like this kind of "sampler" quilt along. I just didn't like not knowing what I'd need in future blocks, like a stronger green for the flower bud. 
Overall, I think my quilt isn't very cohesive (versus, say a pinwheel sampler or a Civil War sampler.) 
All just personal preference, of course. Lots of the LCQAs in the Flickr group look great.
Anyway, my last three blocks.

Totally changed.

Changed layout slightly.

Totally unchanged.

I'm doing a simple cornerstone sashing instead of the stars, so I should be done with the top this week.
