Really nice! Some thoughts... Looks fantastic, and simple to use off the bat. Big buttons equals good. Some of the gray areas look a bit light/hard to see on my screen, but that's nitpicking, nothing to worry about at this early stage. Nice branding, and the layout is great. I'd change the "edit" to "customize this ad" or just "customize" because I clicked on the ad graphic to customize, but that launched a preview. The word "edit" didn't get my attention. Next, I'd put the "update" button down at the bottom next to "clear | download" because I had to look for how to update my ad changes, and intuitively it should be under the editing boxes ("update ad" for the text). I can't find anything else to critique/improve. Nice.
