The right half of painting is very good and strong, bold and well composition, but left half is kind of dim and not sure, bold flower and vase is good and strong, but coffee cup and drape is weak compare to flower on vase, so you need balance out as  strong or simple, maybe use kittle more clear color for drape will work.

Good and strong expression by bungah pisan flower, line in painting is nice and good design too, more like pattern but might say abstract conscious too, little green edge works well. it has a nice heat in painting which creates tropical atmosphere for painting.

Your african boys eye is such a enlarged and more expression of face, it has good lively feeling by bold touch of brush, also has strong light hitting them, it's nice and strong painting.

Victoria
Your triangle composition is interesting concept and water texture is very good so liquid, and dropping down well, triangle could be mountain or lighting shape, it has good potential for interesting painting, continue.
