I like the black font in #5. I like how the leaves are growing off the B in #4. Maybe try the font of "ecology" in #3 with the style of #4, with black font of #5.
Hi 42studio. I LOVE the logo you did for DAVID MEYER PHOTOGRAPHY. I also really like the fonts you used for WILMINGTON BALLET and TIPPENS CLIPPENS, both very classy. Hope that might be a help. Thanks for your effort so far.
