Very nice. I like the multi-coloured wool you used for the bottom. If you had kept the plant behind and not those floral cups/tea pot, your cup-cakes would have stood out better. Change the crockery to plain colours preferably lemon green and see.
thanks for the tips I don't have any other crockery actually, but now I have 3 plain backgrounds for my pictures, one white, one yellow and one green. I'm using them on the new pictures now. I wish I had more money to buy some props to make nice scenarios for the pictures, or time to make them. I think next year I will have more time to think about that stuff ^^
You could consider pictures from a magazine in the background -(blurred to give importance to your lovely creations) or even some pastel coloured sheer fabric arranged in a sweep!(on the plain backgrounds you have!) All the best for your creativity!
