What If? Metropolis - Testing Compositions using Maya

Although these aren't all of my building designs (I only had one modelled in Maya so I just reused and reshaped them) and it isn't my final library design, I thought it'd be a good idea to play around with some composition ideas. Keeping in mind that this city will have different buildings, colours, and trees...I plan on painting over some of these once I render out a few more. Any feedback would be appreciated.
