Is it weird to give this as a present?

I have been working as a receptionist in a music school for 4 yrs and I wanted to give my guitar teacher, other receptionist, and boss each a small oil painting I did myself as a goodbye present with a card when I leave in two months as a goodbye. Is this weird to give them?? I don't want to act like I'm showing off my painting skills or anything and I dont want to give them anything where they think "why is she giving me this as a present ?". I am close to them but not really close. I really don't talk to anyone at work that much but I talk to them the most except my boss who I rarely talk to. I also only work there one day a week but for the whole day.
