I'm a beginner student of graphic design. As I'm learning Adobe Illustrator so I was looking for illustration inspiration on Behance. So I got this beautiful illustration on Behance by Uran Duo and I decided to copy this illustration after finishing this I changed the color theme of this illustration. So this is only for Inspiration purposes. 

Original Illustration by Uran Duo

Created by me using pen tool and shape also I changed the color theme.
