Wish Angela’s sketches were more artistic (for lack of better word)

Was watching s1 e13 and Angela hands bones her sketch saying she gave her a smile and I was thinking about Angela’s background and got to thinking that I wish her sketches were more artistic, as in full realism portraits. Her sketches usually look like police sketches.
There could be valid reasons for that I’m sure and maybe plot wise would seem kind of silly, but just for Angela’s character I wish she had that, if that makes sense.
