It looks like you have extra fabric between the central motifs and the oval leaf border. I would do some meandering with little occasional grass spikes in the green grass from the central motifs out until you get to the border to push the extra fabric out. Once that is done, I would meander in the “sky” section with a few clouds maybe? Once the inside of the oval is done, I would stitch the oval border ring. From the oval out, I would do a few lines out from the oval kind of like sun rays. If that all went well I would go back and add a bit of quilting inside the bigger motifs to add texture.
