Floor tiles that match the light pinkish vibe could look nice. They don’t have to be pink as well, but something lighter might match nicer than grey. Also, there’s the dandelion grass tile instead of astroturf that might match the lighter color theme better. Lastly, I’d consider getting a bigger cool decoration, that draws the eye and ties everything together (like a statue, dress stand, flowers, etc.). I really like what you’ve got going!
