Helium Balloon Ad

Hi. I’m designing an ad for someone that’s going to sell helium balloons.
Any critique, is the phone number info too small?

It’s really super cute! It took me a while to find the number, so I’d suggest that you take it out of the callout and put it reg on bottom like any other ad…

Very nice, maybe make the background color more child friendly, like yellow or blue.

I think you should change the word ‘till’ to ‘until’ and also make the phone number more noticeable
