I like the title, "Bike Ride" is evident in the visual aspects, there is even a neon trail going up and over the hills. The sun's opacity was brought down so you could see the clouds going behind it. That was a cool detail to add just as a random thing.
The colours and shapes in these vectors are simple yet effective, as they create interesting textures and patterns on the buildings, as well as giving them depth. As a result they become more realistic and true to the style of these ancient palaces.
