Like the image as is - particulary like how you handled the light of the horizon and the colouration of the sky in that area. If you wish to do more, might consider doing a little bit of backlighting from below and behind the buildings to give their edges more definition against the darkening of the landscape behind (done well there me thinks)

Another area might be to add a translucent drop shadow for each of the characters (subtle is all it would take...) to match what can be perceived at the bridge and around the buildings. With the size of the characters don't think this is a necessity, but might add a bit to it.

Their also appears to be a white rendering flaw in the bush above your name. Might be a white variation to the flowers, but on first look - appears a render flaw....

Very nice as is - always more....

best, hewsan
