Thank you all, I appreciate the support.
I do think that maybe, on such a small bag, I used too many fabrics, it's too 'busy' I think the person it's aimed for will like it, but for the next bag I'm going to try reducing the number of fabrics on the main side panels to three and altering the proportions of colour by cutting different width strips. I'll use one more for the bias and lining.
The next bag is in shades of blue grey and some silvering on one fabric, so we'll see how it goes.
If we had an icon for cutting up bits of coloured paper, and colouring pencils, I'd be using that here
