You have all the elements in there, which is a great start! So thank you for completely reading the specs.
Here are some comments: "The Emerald City" is a bit hard to read over the logo and believe it should be under the logo. In doing that, I'd suggest part of the bottom of the circle be trimmed off to create a horizontal plain that the typeface could sit under. The colors are a bit too primary/bright. I'd like them to be a bit more 'cool'. The ballon could be red with the white "H" in it. And I'd like the road to be more like a cobblestone. I'd lose the tree and focus more on the leaves and shrubs.
Hi and thank you for the feedback - made the changes to cobblestone path and red balloon. Can you elaborate a bit more on 'cool' colors, do you mean more dull/faded? Thanks, Catherine
