I am a painter of 40 years, have done well with it. Even after this long I am still willing to learn new things. I have taught over 30 years and i always tell my students when you quit learning you are through as a n artist I enjoy your site and look forward to learning more things, Thank you for sharing. I don't pencil draw much but draw with oil paint. I block my subjects in with a gray color that vanishes when I paint, so your site will help me in some ways. I am now retired from 60 years of doing business in 5 fields, Also now a kidney patient on dialysis, Not being able to do much work now i have turned back to p[ainting. I have over 300 paintings sold in several states and overseas.
  The oil bust in the 80s stopped a lot of paintings sell and the drouth also husrts artish here in the Hill Country of Texas. It was picking up but now the oil glut has slowed again. But this does not stop me from paining. 
Thank you for your site
