Same thing as with the oil picture, lovely colors and expression, red was a good choice. Work on composition, it seems you lacked space on the right, and the left  side has much less details. You use your left hand? That could be the reason why. Remember there is a bottom which carries the weight of the picture, the weight of the whole compostion should be either in harmony or intentionally not, to show the meaning of the picture- then the picture flips in your mind and the meaningful spot is the one which is the most visible.  You don't limit your art  though and that is the most important, I am proud of you.
