I redid that one Marco, I think I did what you mentioned. I have a hard time with the sharpen tool. Nothing seems any different when I use it.
That's odd re: sharpen. Do you use photoshop?

I like your redone version better. I notice the 2nd version is smaller which is cool but it looks better larger. I'd suggest darkening that ice on the right mid edge even more though. Perhaps 20% more.
