Grace, This is just beautiful fantasy, i really love the idea of the butterflies flying through the myriad colours. there is flowers and petals in layers, also buttons as well. the fact that you have done it in marbling and then render is very effective. It gives me a happy feeling and a smile. The whole artwork is filled with images, no white space. and the colour scheme works coherent too. The only thing i would criticize is the darker areas where it is dominant in terms of it black colours, but overall really lovely textures and overlayers!! well thought out !!
