I like this layout the best so far. Do you think you could use the extra brown you've got laid out on the left to make some kind of trailing stem? Maybe the green could be placed as leaves...I'm new here and haven't even made a quilt yet so I'm only going by looks. I might try to use the extra red to make a few more flowers and connect them with the trailing browns as stems. Maybe that's easier said than done, I'm sure it is.
I admire you for trying to do this. It's hard enough to flesh out your own vision sometimes let alone someone else's that doesn't match your taste. Good luck. I'll look forward to seeing it finished.
