Sculpture carry on

I decided to use different methods to smooth out my sculpture. I used a metal kidney, surform (grator) and wet and dry sand paper. 

Here are the photos 

My sculpture is a lot smoother but it could be better as it have wholes in but I have chosen to keep then and keep the flow of the casting plaster as shown on the 1st photo. Also I have chosen not to sand down all of the sculpture as I like how it it looks like something has been poured over it, as at the bottom of the sculpture there's a ripple and under the smallest sticky out part. Now I would like to keep the colour of white but probably paint it or spray paint it.
