My intro through and art piece

I joined one online art class, in which they asked to submit an art piece to introduce yourself. It could be 2D, 3D, on any media and of any dimension. I wanted to put so many things in it. But, I ended up with a quick and simple sketch with colors. It's quite rough and also I didn't know how to draw the background which looked like in bokeh photos.

By this piece, I intended to show an independent girl with zeal to learn through books and her love for nature as she's lying on green grass and colored leaved tree in background.
