Vivien - I agree with you, pointillism is more of a mathematical equation than emotions - even tho, by the time you finish any work on that technique, you are full of a lot of emotions related to it
I like, I think it is very interesting, also, you can learn something from the artist, such as how much endurance and patience that person has. It is a tedious technique and it takes a lot of concentration and with a simple few extra dots you can unbalance the whole piece.
