hmm well first of all the colours are perfect. i like it how the orange/pink bit stands out and also these little confetti-like blobs of colour i like geometrical shapes and the MO letters (whatever they stand for) in contrast to the light background. and i like the frame with the signature which colour matches the colour in the middle. i dont know, everything is just so balanced, and i love simplicity and this kind of design. compared to the design samples ive seen lately, this one is the most harmonious.
