I would not call these two paintings as "色彩绚丽". In contradictory, I experienced a kind of depressing. Strange to see half of a "sinaasppel" hanging on the tree, which also occurs in your "集体作业". Is this a sort of symbol?
By the way, I am a big fan of you. Had been in your "D" city several times and next time try to find some of your paintings.
