The first one reminds me of Miami Beach, and might be someone's futuristic take on it, except that there are hills in the background that shouldn't be there, and the lighting is way too indigo for Miami. I'm trying to figure, where in the world are you going to get a shoreline like that with that kind of vegetation?
I'm also thinking, WTF is that building doing in the water? There is going to be mucho wave stress on it, and the beach is going to be screwed by its disruption of the wave action. Not to mention that its probably a long way down to bedrock in that location, given the lay of the shoreline and the land.
The second one could be any bit of seamy futuro-punkish urbanscape. Take a modern structure of once-fashionable taste and apply bomb damage to it and its environs. Add a roller-coaster structure to clinch the absurdity of the scene and nail it as a punk fantasy.
