OK This is my opinion on why there is a difference between the lacquers and oil/acrylic paintings he did !! First,, it is a different medium, so he was somewhat of an innovator in that technique !! Second,, did you notice the drama in the lacquers ?? They are very powerful paintings !! Not so in his oils/acrylics,, they are quite tame by comparison !! So as I said before,, it is not so much the medium used but the subject matter that counts,,as well as a few other minor things !! Like sales records !!
