Hi there,
I was happy to read that you are looking for illustrations with old-style feel. Being a traditionally trained old-school illustrator and a comic book addict, I can offer all the varieties you enlisted in your call (pencil, pen and ink, also watercolours or other combination of traditional media). I normally deliver high res scans, but I can also send the originals upon request. I would first deliver pencil sketches and proceed with the illustrations only after they are approved.
For an idea about my skills, please kindly check https://www.freelancer.com/u/ddimitrovska. If you are interested, we could discuss all further details over chat.
Kind regards,
Dusica
