Might I suggest you anti-alias the edges more, they look really grainy now. Other then that, love the composition and color use. Any chance we'll see more landscape oriented work? (easier on my desktop)
You know, it would look cool with shiny lens flares on it, so I think I might edit it in the near future, but like I said in another comment, its meant for a phone bg, so I wasn't worried about detail that much.
