Light/Face small studies [watercolor]

My last work before Matura exam ;3;'' (called the exam of maturity in my country)

I said that I'd like to draw more full scenes, not just characters, but at one day I felt insecure about my shading skills so...
STUDY TIMEEE!

And I don't regret being insecure about it, lol.

I'm not sure about composition of it, and if version with texture is better xD'
