This painting is amazing! You're mastery of the brush is beyond admirable and your creativity and ability to push the boundaries on the abstract genre are amazing. Congratulations on this amazing masterpiece.
Humm... Is this an assignment or your own personal work? Because if it's your personal work then one could say you are going abstract. A nice style, though, all colors and shapes, no lines, no specifyed background so that the whole picture gets a different emotional dimension.
The only advise I could give you is to go lighter on the browns, or, rather, on black, it kills the colors and adds uneven weight to the painting.
Beautiful work also.
