#39 and #40 are nice but we do not feel like they are designed to reach the type of clientele we are seeking. #41 is the one we like best because it is a bit more abstract and has much more widespread application.
Can you try to change the font to something more rounded and organic in style like 'Gulim' font? Also, please make 'Land Design' a bit smaller, and try to add a bit of blue to the logo and then change 'land Design' to the same blue and remove 'let's grow there' from the design.
