It's remember me klimt with fatal women and patterns on their hair. Well done for proportions nd shadows, but you hve to make it live iwth colors i think.
to color a pencil drawings isnt evry easy but maybe i give it a try and use my aquarell colours or some of my acryl colours ... coloring with photoshop and co. isnt my thing (i cant add life into CGs i prefer traditional medias)
btw. some of your newer works are pretty much inspired by klimt (his "Wasserschlangen" f.e.)
In fact i love klimt, and that's why i whatch what you've done here ^^, and also because you're talented! And traditional media are amazing, especialy aquarell i think. Hope you'll try someday to color it, it would be very beautiful!
