Hello friend I am very happy with your coffee art and while participation you have shared a step by step procedure with us along with your pictures which is looking much original and creative also.

Secondly if I talk about a tree like structure that you made and then fill it with coffee colour then I must advise you to don't use any pen while making the coffee art because in this way your colour may mix up and best advice from me is to just use thick coffee colour for making a sketch.

Overall it is well presentable I wish you success
