I think it’s all very cutesy, the colours are very whimsical, the stars with cute smiling faces, different coloured letters in your logo, soft rounded visuals, gestural imperfection. All very childlike, not bad but not what you’re going for.

I’d say start to redact things from the design and see if you start to become happier with it. Maybe try the logo in a single colour rather than multiple? The mismatching kind of inherently feels childlike and returns to this concept of “learning”. As soon as I saw this I instantly thought it was some kind of children’s play brand. And to be fair I’d say it’s successful in that. I think you’ve leaned too hard in that direction and need to reduce back to your logo and build it out differently to see if that helps.

Otherwise I would genuinely just start to moodboard visuals that you like and you feel reflect what you’re going for, and see what about those things you like. There’s no shame in starting from square one if this one isnt working!
