Lois van Baarle is a Dutch illustrator and concept artist currently living and working in Utrecht.
Her digital painting style combines the kind of lively, springy drawing sometimes found in animation and gaming concept art with Art Nouveau-inspired flowing curves and sweeping design elements.
Her website portfolio is divided into basic sections within which are individual themes or projects, including some sketches from life. You can find additional work on her blog and deviantART gallery, as well as her society6 and deviantART shops.
Van Baarle has had tutorials of her techniques published in several digital art publications, and there is a FAQ on her website that includes some digital art resources in addition to background on the artist and her work. There is a brief interview with Van Baarle on Chaos Magazine.
