Need help

Hi , I am a beginner and just stated to paint with watercolor as an hobby . I love the effect of having the edges of the paint defined ( hard edges ) I noticed on this painting beautiful fades with dark defined borders . Is it a paint ? Or paper? Or special technique ? I tried to achieve this effect when I paint with my paint (Qor ) and beginners paper and it's not coming out this way ( I was hopping someone can give me some incite . I would be really grateful.

Thank you
