Transform Dull Classroom to Engaging Scene

I'm looking for a realistic digital artwork that transforms a dull, unengaged classroom into a vibrant, engaging learning environment.

Requirements:
- The artwork should depict:
- Students interacting with each other
- Teacher actively engaged with students
- Classroom decorated with projects and artwork

Ideal Skills and Experience:
- Proficiency in realistic digital art
- Experience in creating engaging classroom scenes
- Attention to detail and creativity

Please provide samples of similar work.

I would like it to be one picture. On the left the dull calssroom with no engagement and in the middle the picture starts turning into a vibrant, colorful and engaged classroom.
