These are very interesting. I'd like to see roots more like in #14, where there is ground that the fuel dispenser is sitting on, and the roots are a little less distracting.
#55 is very nice, but again, I'd like to see the dispenser sitting on the ground, and I'd like to see less roots, like what pakde has done. I love the font, and the rays are a nice touch. Consider making the sky blue as well.
Thank you. I look forward to seeing the new versions!
