There is a gift art event in this Chinese furry forum:
http://furstart.com/
They have free gift art event every month. Members can post any requests, and artists can pick any request they like to draw.
And here are the sketches I did for last month.

The guy requested this by leaving some poems about some characters from the Touhou series, and ask artists to draw the " feeling," "artistic conception" of the poems and of his own character. It was very hard to understand, so I just drew his character as one of character in the Touhou series.
