Let me introduce you my artwork for collaboration NFT256 WORLDS. 
100% vector. Adobe Illustrator + Wacom Bamboo Tablet.

My work was one of 90 arts from 90 different artist from NFT256 Team. You can see all 90 worlds in that video:

1. First of all - looking for concept.

2. Dirty Sketch.

3. Grayscale sketch.

4. Looking for perfect colors.

I choose that color scheme. Romantic and Dreaming atmosphere. That's what I need here.

5. Another sketch and perspective guides for phonebox.

6. Clean line drawing.

7. Basic coloring.

8. Final detailing.
