You should check out Adobe Lightroom! You can do some really cool post production, like getting rid of that noise. I totally dig that you're into photography using a cell phone. Just goes to show you don't need a fancy camera do do your art. Here's my edit with a little cropping, clarity, and noise reduction.
I really like it! a beautiful shot, but same as oldhippy, I would like to see the bottom feet and level the lines that are in the background ( a little distorted).
I can't believe how nice of an image these cell phone can take!
I mean, I never thought about doing any post processing on the image from my phone. Just didn't think about it. Just a blind spot in my thinking about what the phone can do.
