You should redraw this, as a simple B+W in charcoal on a good surface rough paper, scan in at 600dpi and post that and do a colour version, do some sketches in charcoal and with coloured charcoals too.
I like you style which is like Joel Jurion, check also Oliver Vatine, Milo Manara, Stephane Roux, Humberto Ramos. Alos have a look at Rocking Jellybean and his site, posters and cd cover art. Krash Zone is worth a look at too.
Some books worth looking at are the Disney art of- Frozen, Big hero 6, and Zootrpoolis. Books by Focal press, various themes.
Hope this all helps, draw some girls with platform high heels and some femboys!!
