Weekly practice 08

my teacher told me : when your sketch relationship is complete , color would never be a problem .
i tried in this practice , i think ...
when sketch relationship is complete , make color diversity casually (or even randomly) , it wouldn't be wrong (cause the structure still exist) , but about expression... color is still a very important element .
a friend told me : don't think too much , try to express by your intuition . ok maybe later.
