Family painting : Abstract Graffiti- Is less More? When to quit.

We could - or should have stopped somewhere between these two. A bit too pink - 

They thought it could make a good birthday present for Daddy as it is his birthday next week.

So it says : Happy Love, Iris , Daisy , Giles, Emma

They continued and love fluorescent paint - I however wish I hadn't bought it! 

And then painted our family on top, (mess) and then painted on top again.

Oh no - do we give up or try to continue?
