Embark on a delightful illustration perfect for a birthday celebration. It showcases a blue cartoon hedgehog character, known for his speed, leaping joyously above a landscape made of blocky trees and a pixelated explosive block, hinting at a digital adventure. The backdrop interestingly merges with a simplified skyline of a historical northern city, blending in through a creative fusion of street art techniques that add an avant-garde vibrancy. Central in the design, the number '7' takes the form of in-game blocks, tying the fantastical and adventurous themes together for a memorable seventh birthday.

Generated with these themes: Sonic, Minecraft , Newcastle , Spray paint, and 7.
