It was VERY VERY hard to let go of.... I have an extremely hard time letting go of any of my paintings, like sure its great someone liked them enough to purchase them and hang them in their home, but each piece I paint is a part of me and my life, they are my babies..LOL so it is hard.
but when you find someone that understands the piece and really loves it, at the same time its like letting her be adopted by a family that you know will love her like you do, so in the end its a bittersweet experience :)
