I experimented a few days on this. Refractions will remain on my macro bucket list. This is the best I could get, but it is still not what I wanted. I did like this one, because of the spring flowers.
I think this is a great start and pattern choice! The big thing is being able to get a narrow aperture (like f/14 or f/22) and for that you have to figure out a way to jigger a tripod above it all, at least that's what worked for me.
