Hi ! I like the look and colours of your logo. There is something about it which reminds me of BP and their logo. Ofcourse they have decided to make their image more environmentally focused and have chosen this look too. Perhaps you could make this logo more distinct for Green Star blinds. ? As for typeface, I like the look of #8 so far. For the logo too, please keep in mind I would like people to see the symbol and link this to my company or what it does. The logo will be on the bottom of every blind which is made by Green Star Blinds.
#105 uses a stylized leaf shape to make it relate to the BP logo even less while creating a new environmental symbol specifically for you. As the layers of leaves overlap it increases the "shade" of the green and uses a 6-pointed star rather than literally six stars.
#109 uses the six stars to show a progression to your current environmental destination in the green star rating system..
The type for both logos is bold but approachable. I have steered away from being literal in showing "blinds" pictorially as in #68 and #69 since it's unnecessary to show blinds since your name includes the word itself. My aim with these logos is to relate with recognizable environmental symbols while creating one that stands out as being uniquely yours.
