Shall I change paper or blend more

Shall I change paper or blend more - student project

Hi Jen, thanks for your class. Oil pastels are so fun.

I draw some faces and feel the result is quite rough, not smooth enough. 
I wonder if my paper has too much texture or I did not blend enough.

Kindly advice. Thx
