I like the use of colour in the EcoPlan design example provided, but I think it looks too plain and dour. I would like something using similar colours, though perhaps with a little more green (not all green, but with more green than blue) and with a more lively-looking design/font.
I would like the logo to look somewhat lively and upbeat, so the font used must fit that requirement.
Perhaps the word could arch up slightly left to right? I don't mean to make it diagonal, but perhaps in line with the basic outline I have drawn and provided in the images. The writing doesn't have to be as "bubble-like" as the one I provided, in fact I would prefer it not to be. The scanned design is simply to show you what I mean by "arching up slightly", not an example of what I want.
Feel free not to use my sketch if you have a good idea that looks different. I don't want you all to feel you need to stick to my sketch, that was just one idea. Feel free to be as creative and unique with your designs as you wish.
