Ben is correct, you should lose the drop shadow, and you definitely need to show the leg of the G.
I'm not feeling this at all...
I like the font, but slamming it into the top of a building detracts from it.
Are there a lot of trees growing on rooftops where you live? If not, then your potential clients may be confused by the use of a tree up there.
I'd make the width of the building the same as the width of designroof.
Give the building a door. (maybe make it green).
You can make it looks like a real title on a building's roof.
The "i" don't looks like a "tree" as supoosed to be, but more like a pin !
I like the overall concept, however it might look better without the drop shadow also, like other people have said it would look better with more of the type showing. maybe try an upper case type as they're all 'above the line'.
You are going somewhere with the 3rd design. Work on it. Consider omitting the horizontal line there.
This logo is lacking readability in a big way. The focus is definitely on the object itself and not the word. I would revisit this.
i really like the design might u display some more lower part (visual) of the font typo..
I like the feel of it.
Definitely show more of the text, especially the bottom half of the g.
Be nice to see it a bit bigger.
Personally I would take off the shadow from the windows/squares and maybe make the black a tiny bit lighter to give it a 'print fee'.
Nice work :)
