On these here #14, #15, #17 I put the symbol on top and played with the colors and font. On #15 please note that I tweaked the grassy piece forming 'H' for a better visuality.
Same thing here #16, #18, #19, #20 as well. I also tried different layouts.
I just don't wanna throw a lot of them at once and get confused. We can always work and change the colors once we are set on the layout and specific positioning of the elements.
Please feel free to ask anything that may come to your mind to try for a better outcome. We will work all the way till it realy suits your needs.
Thank you.
