Nice design but I would put the new URL above this: Because it took me several seconds to find my generated URL. Good work tho.
You know, the new URL is like below everything and it's hard to find. At first I thought your tool didn't work.
it looks washed out...need something to cause it to pop out...maybe a bolder color... one thing you might do is to make the urls a little easier to pull out. you also might add a page about why it is valuable to hide the long url... hope that helps...
Above the fold, the site looks good. However, below it is way too much clutter for a professional website. If it was a blog it wouldnt matter but since you are providing a service I think you should tidy up a bit!
