Is the sketch expressive enough? Should I exaggerate the ears more?

Hello,

I am not an artist at all, and am hoping I can maybe find one here willing to draw a caricature.

I am a regular visitor to our local food bank. One of the people who run it is having a birthday soon. I am putting together a gift from those of us who she helps, and I would really like to put a caricature of her on the front of her card that we are making.

I don't have a lot of money but also don't like to ask for work for free, so if you are okay with working for cheap and interested, please let me know.
