Playing fun sketches

If I don't feel too tired after supper at night, I like to do some sketches simply just for fun. I did not plan to sketch for a specific project, but sometime it may turn out something at the end. I think art came out naturally from inside of me just bring so much joy, and this joy will be continued to my commercial projects. This is what I sketched lately, I am eager to see if any elements may turn into something in the future~
