Definitely like #27 a lot, the other two seem a little too plain. would be interested in seeing a different typeface for font - the serif font might be a little too stuffy.
Love your shape and style for Entry #27,30,31 and I would like to see a tree worked into that as I outlined in the creative brief. I also like how you underlined it and had the leaf on the end. Could you make the green darker. Thanks!
