Hand Drawn to Cartoonish Digital Image

I have a hand-drawn picture that I need transformed into a digital image with a cartoonish style. The final product should be in JPEG format and suitable for printing onto a t-shirt. The pencil needs to be in white as it will be on a black/dark grey/navy blue shirt.

Ideal skills for this project include:
- Proficiency in digital illustration
- Experience with cartoonish style
- Strong understanding of print design requirements
