Mmh- Not bad, but that tile looks a bit weird for a road, at first sight I even thought it was a railway instead... xD Well, maybe if you just make a little wider it may look better, or perhaps you should try with some other tile, one without 'edges' if you know what I mean.
Also, shouldn't we be able to see the name of the person who is talking somewhere in the text-box?
Edit: Heh; I never thought such a small edit could make the road tile look so much better. :thumbsup:
