very interesting your number 58. Your work is making us thing about a molecule of MIlle Ottani. So, try to mix your number 30 with your number 58, replacing the world with the ball ( an orange one).
The number 63 is very interesting!! It is not so simple to visualize immediatly probably because of colour mix. Organge probably is good, it's energy, but try to change the blu in something else (black or so on).
