Just came back from my visit to California. Love the Spanish/Mexican influenced architectures. Had great time visiting friends and simply wonder around to sketch. All were done with watercolor plus white gouache.
About 2 hours total. Sketched in the overall shape the first day and completely gave up after 30 minutes. After a night of sleep, crawled back to finish it off.
Similar story... except the painting portion went a lot faster. About 2 hours total.
Hanging in Starbucks while drinking nice cup of coffee.(Thanks Kevin!) About 1.5 hours total.
Change pace and went directly with paint without the usual color pencil drawing. about 1 hour.
