I reviewed the Gl.Emp. flats yesterday on their web page ...
It is a beautiful flat and your painting looks promissing.
Attention: the light you gave to the picture (right above) mathes perfectly the second picture, back side of the character, but conflicts the lighting given to the front side, I mean 'neutralizes' the light, which makes the reading more difficult....
You can surely help by adding lights on the horse aswell.
