Share a little about the materials, processes and techniques used to create this piece. For lack of any inspiring outdoor subjects to sketch I choose this photo of an abandon house because I thought that the perspective would be a challenge.....I was right! Especially the dormers, they are still not correct. I can't figure out if or where there are any reference points to use in which to gauge there correct angles. I have already gained a lot of insight about perspective while trying to plot out this house. For instance, Without using the vanishing points to find the correct angles I would never have guessed these angles were so severe. For this project I used Creative Mark, Reflections spiral bound field sketch book with 70 lb cream paper. Wolff's carbon 2 and 2B, F, H and Draughting pencils. Is the piece for sale? No What are you most proud of? That I finally figured out the scale of this house in order to have it appear similar to the picture. What advice would you give someone starting this project? Probably the course "The Art and Science of Perspective" would be helpful in learning how to draw building. I've signed up but decided to tackle this class before starting it.
