D*mn, don't pay attention for a minute and you got to read ten pages just to get back on track here.
hmmm, suggestions, well, if you haven't already thought of them, you could add generic international signs, what do I mean by that?
I'm glad you asked.
;D
Around here, you can be driving along and see some large signs with picstures on them, so anyone looking at them can understand what they mean without knowing the local language.
as in, motel ahead, airport, so on. something that will add to the enviroment.
Plus, like you already planned, make up some billbords for some imagined(Not nessarily imaged) products, like shampoo, some resort or attraction.
Buckle up and be safe signs and so on.
Oh, heres one, big low billboards, the kind you always see in TV shows and movies that cop cars and cop motorcycles hide behind to catch speeders, and so on.
Large overheard billboards, the kind you see on highways, you know that have a poll on either side of the road with the sign up overhead.
Now, I hope this is the kind of suggestions you were looking for.
Or else I did alot of pointless typing.
;D
