Spin Brush - Issues with symmetry

Ok so quick question - I have recently started using the Conair Spin Brush and love it, however I am right handed and no matter what I do, no matter what angle I attempt, the right side of my head will not curl nicely under the same way the left side does - the right side's ends are always flipping forward and then start to turn out. I have tried using my left hand and holding it at the same angle I do when I use my right hand on the left side of my hair, but to no avail.

I assume I would have this problem whether I used a spin brush or a regular blow dryer and brush, but are there any tricks to getting the results I want? I am no pro by any means, so I am somewhat awkward when styling my hair in general (which is why I got the spin brush in the first place, so I don't have to hold both a brush and a blow dryer), but it is frustrating when no matter what I do, I can't get both sides to curl nicely and naturally in.

Any help would be greatly appreciated!!
