Thanks for the tips Raymer! I wasn't really familiar with the procedure yet. But I think the last logos you've submitted (#36, #35, #27, #26) are much better. This is more what we are looking for. Could you adjust #36 and #35 in a way that there is a leaf instead of a lightbulb? It's not that I don't like the lightbulb...
#27 and #26 look nice too. The font suits more for an architectural brand in my opinion. Maybe you could simplify the color use in the font to make it a little more minimalistic.
