Alvin's balloon ride

I know, I know, it's not the best drawing of Alvin but it's the first time of me drawing him, so that's why. Plus, in case your wondering, the reason why you can see Alvin's legs are, you know sometimes when you wear something long and loose-flowing like a dress, a robe or a gown or in Alvin's case his shirt. Then you get on something you most likey sit on, like in Alvin's case his balloon. With that thing that was covering your legs isn't covering them anymore, same thing. Plus, this is just my guess as to what Alvin's legs look like.
