"Improve" means to increase the level of quality. "Enhance" means to take one element and lift it to a greater degree (the old meaning was simply "to make higher"). You can see there may be some overlap, however "improve" can only be used in positive situations. To illustrate: "My bad mood was improved by her actions." = you felt better. "My bad mood was enhanced by her actions." = you felt worse.

Improve means to become or make sth better but Enhance means to make sth look better by increasing its value or beauty.
