Indeed the style in the USA is a bit different than in Europe....
My favourite is the soldier of Pete Culos 3 ... outstanding shadows and highlights, colour mixes, the painting is really coming out of the frame !!! at least a half-round flat figure however!
An idea to keep is the crystal as background for flat busts ... Congratulation!
Also magnificient Astérix and Obélix painting from J. Russel ...
