we beginners have a hard time coming up with ideas
WE??? No, no no, we are nto beginners. You might be a beginner, but I am not even in the beginning
Actually I think it is pretty good. I wonder for a while what it was, but you work around with it, until I couldn't recognize it.
Now, in my personal taste I like vivid colors, and preferable darker. So I woule add some blue, which represents water, and maybe some green, unless you are preparing your desktop for fall, of course
But then, this is my personal taste, and I think I am bad in designing (and I am sleepy right now)
