We prefer your previous concept. Would you mind explaining a little where the idea came/ any inspiration. We like it, we are trying to better understand why.
Thanks for your feedback. The idea started when I read through the 3 key points you wanted to convey through the logo: #1 - We are friendly #2 - We grow your rewards (tree) #3 - We simplify your life A tree grows from the ground so the lines shooting up gives a sense of dynamic growth. Rather than illustrate an actual tree I thought that a more abstract / simple style would get the message of simplicity across. And the colours are the icing on the cake as far as adding the friendly vibe / feel. Another thing I was conscious of was giving it a non traditional feel as it's an iphone app after all which suggests trendsetting / new ideas etc.
Hopefully this helps. Let me know if any further queries.
Slightly edited version - I have adjusted each section of the tree to be different sizes to once again emphasise growth. Also added the sun rays which adds a little movement and extra excitement. Finally just tried integrating the text more into the graphic. Cheers, Craig
