Hi there,
I checked the reference illustration you provided and, since I'm sure I would immensely enjoy working on your characters' design, I would like to express my interest for the job. I'm very fond of high quality anime and manga myself, so I'd enjoy the work. Following the best anime traditions, I work old-school, by hand, so my offer is for original, custom, done from scratch handcrafted art in pen and ink and watercolours.
I would first deliver pencil sketches for approval and then proceed with the full illustration.
If you are interested, please write back to discuss all details over chat.
Hope to hear from you,
kind regards,
Dusica
