Here is feedback from the team:
"I really love the character! I would like to see more options of the fonts Greetles.com and have the tagline included."
"I like the latest image (entry #3), but would suggest maybe adding some little wings and working in some additional colors (i.e. yellow, red) to make it look more vibrant overall. I have to compliment the artist on the facial features- it's a cute expression!"
"I do like logo #3; however, I would like to see more color in the greetle character. We need to bring it more to life! It's the best design so far."
I agree with the comments above, you are going in the right direction.
Thanks!
