The 4 Ps

In mathematics,  I plan to keep 4.4 same for all but wanting p1 and p2 for the two expressions.  This I believe is nature's laws. While my readers want change in 4.4 itself. 

Now I am concentrating on art. Left mathematics with the above thing in hold.

I shall be concentrating on Perspectives,  Proportions,  Planes and Perpendiculars. The 4 Ps. The 4Ps will be aimed for with DMAIC and PDCA in mind.

I aim to draw like Terada Katsuya, but for comic drawing.  His book has arrived. 

Thanks for the book.
