My Mighty Mac ~ sketch

The sketch
I'm not sure how much detail I will include
 in the final painting. Better to have more detail
available than I will need than not enough. I can
edit easier than add. Notice I lowered the horizon
line in the background in the lower left.
Cecile Graven made that suggestion & I think it works. 

This is the altered image enlarged to 15" x 23".
 Notice the dark area in the upper right(storm clouds?)
 I love the lens flare in the upper left and the brilliant
patches of light which creates a stark contrast to the
silhouette of the tower.

I've been monkeying around with this since my last post. I decided to enlarge the altered image and use that for my drawing. It didn't yield a lot of visual info regarding many details so I had to wing those myself. The enlarged drawing is approx. 15" x 23" but I'd like to take it up to 22" x 33". I sent an email to Framing4Artists requesting a quote on a custom Masonite panel with a cradle depth of 1 1/2" and the price was reasonable considering the cost of matting and framing a piece that size if done on paper. I've never worked on panel before so this would be a new experience for me. It will have to be primed with painters gesso and sanded. Not sure if that's doable for a winter project because I don't have a basement or other appropriate workspace. For now I plan to practice on w/c paper at the current size to get ideas for the final painting on panel.

Btw, one thing the enlarged altered image did provide was an idea for the background. When it printed out the sky in the upper right corner looked like dark storm clouds rolling in from the east and looking (appropriately) ominous. I think I'll also keep the lens flare on the left side of the tower. I like that effect!
