What a great topic! Love your coloured ganache, the colours are so vivid. If I could do every cake in my own style (free reign on design) it would be awesome as I feel my own designs are defineatly the best, and are the ones I most enjoy doing. So if I was to define my signature style it would be freehand drawing and painting on a cake.
