What I want to be when I grow up. this is an artist. even now I’m not drawing very nicely, but I think in the future I’ll draw beautiful paintings. I won’t buy them from me. and maybe they will. I still don `t know. for when someone else has a birthday, I can easily give them pictures. many will like them. why I want to become just a painter so simple. I really like it and I draw only when I have inspiration. when there is no inspiration then drawing will fail. and still artists draw in silence. I still don’t know if I will be an itch or not, but I think so.
