Sergio Lopez is a painter based in the San Francisco Bay area, who works with landscape and figurative subjects.
His landscapes, both in plein air and more refined studio works, are based on direct observation. His figurative works are more interpretive. Though painted from life models, his figure compositions often incorporate invented decorative elements, floral patterns laid over the figure and background, or patterns on drapery that intertwine with the figures and their environments.
Some of the landscape images are reproduced large enough that you can see his nicely textural laden brush approach.
Lopez paints primarily in oil, but his website also includes sketches in gouache as well as drawing media. The home page of his website serves as a blog, use the menu choices to access his portfolio.
