We like what you did on #62, but instead of the "A" with the circle around it, could you make one with the A like on #44? And also have the "web services" a little bigger and more readable.
We like #78 just without the circle around the A-symbol (example like what you have as the A-symbol on #61.) And then have the actual "Aldea" and "Web Services" a little bigger as well.
