Cool. I used to have my status bar transparent. I'm not sure why I changed it to black. I probably had a wallpaper at one point with a color at the top that was making the status bar icons hard to see. I'll have to look into livepapers, although that sounds like something that might eat up a little extra battery life. Due to my profession, I'm on the phone a bunch during the day, so I have to weigh heavily the need for battery preservation vs. fuctionality/viewing pleasure.
I know the battery thing is a tweak. I'm just saying, for the sake of minimalism, I prefer just the number (not even the percentage sign), instead of the number plus the circle. You could always set the number to turn red when it gets below "x" percent. Whatever you like best, though. I don't meant to be rude or sound critical.
Is that "sunny" weather icon one you swapped out for the stock ones? If I recall correctly, for the brief period I was using Weather Icon to show the weather in the status bar, I recall seeing a the "sunny" icon as a colorful animation of a sun, basically like the one that shows in the stock Weather app. I could be wrong though. Wouldn't be the first time.
