stitching leaves and tulips

By the time I finish this piece (it measures 12x14 inches), I'm sure you'll all be sick of seeing it! In my bit of sewing time this afternoon after my lap swim and lunch, I added some fused leaves and stitched them. I may still add a bit more shading to them.

Then I decided that a couple of the tulips might needed a little accent with a bronze metallic thread.

I still have some tulips to stitch and I'm thinking about how I should machine quilt the background above the the tulips. Any ideas? Should it be stippled, zig zag stippled, straight lines, leaves? I often have a difficult time to choose the background quilting design.

Also, I typically like to add some hand embellishments before I'm done, so this could take a while! I'll move on to another piece though once it gets to that stage.
