These are the delicious, modern-meets-Art Nouveau illustrations by Marina Mika. The Croatian artist does all her work using just pen and ink, but her results are lush and highly-detailed and positively gorgeous.
Mika includes unexpected elements in many of her illustrations which somehow work, even though they shouldn’t. (Glamorous roosters?) Most of her pieces include just a single color – usually primary – which sets the scene and sometimes calls out some of the more unusual details in her work. Her judicious use of color is truly remarkable and thoroughly effective.
