Dandelion Portfolio

I've been spending a bit of time on Redbubble and I've noticed that everyone (slight exaggeration) has a dandelion shot in their portfolio. So on the weekend, I decided to go out there, find some dandelions, and see what I could come up with.
I'd really appreciate some feedback on whether any these treatments work, and also how they could be improved!
