Personally I would turn the strobe light power right down and move it to the front a bit.  This would make the yellow light your main light source and the strobe light the fill. 
Try turning down the iso on your camera to get rid of some of the noise 400 iso is unnecessary as is a shutter speed over 1/250.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
