[UPDATE] Forgot about 3 billboards, they're replaced now. Sorry about that.

Starting with LC's Dukes, I'll try to replace all billboards in GTA IV. So stay tuned!
Because GTA IV's engine can't handle heavy textures, I had to keep the resolutions of the ads the same as original.

Be sure to check my account for other boroughs. Whole map is completed.
Click on the second video to find a link for all-in-one whole Liberty City overhaul pack. I had to use mediafire for this one, because the file is too big for GTAinside.
