Alphonse Mucha. I absolutely adore his work. Mostly of elegant women and spaghetti flying hair.
Nicolas Gouny, a french painter had this posted on his deviantart website. I love the witty romance that hes depicts in this picture. His lighting from the sunrise aesthetically pleasing.
By God, she is one of the best I've ever seen. Her work is super chic. Allison Torneros does alot of mixed media and is a graphic designer/illustrator. She works with alot of graffiti too.
These works of art have already begun inspiration in my work and those work are now in my portfolio actually. :) So... find inspiration! Leech off good ideas! You arent necessarily copying. Its more of a personal journey of finding your own original, unique, creative style(s).
