Ballroom dancing watercolor painting

I have further worked on the ballroom dancing watercolor painting last night.  As you can see, I have added a wash on the gentlemans dancing gown.  What I learned is that I should prepare a large watercolor wash instead of trying to mix more in the middle of painting it.  I did that in a flat wash which uses more color than other washes.  Because I need to keep the edges wet between washes, I have a hard time doing that and mixing more paint.  In other areas of the gown, I have use gradated wash so that the final result will show variation of the dark color instead of one flat pure grey black ballroom gown.
