Your thoughts please?

I have finished quilting Penny and Fletcher for the Festival of Quilts and I am going to bind it today- in white as that's the only thing I can see working. I thought about black but I think that will show every little stitch gone wrong when it comes to the very top of the quilt.So, this morning I fabric painted in a few details and the shadows to make it stand out from the blue background and add a bit of dimension. I am now wondering if I shouldn't have and I should have left it as it was! I have a choice, take the iron to it and set the colours, or throw it back into the washing machine after I've bound it and wash it all out.Here's what it looked like before (and before quilting- I forgot to take an in between picture)...Here's the original photo...And here it is now...So, honestly, what do you think, have I made a mistake?
