Hey there!
Could you provide some references for what you'd like in terms of style and level of detail? My process would be to do this by hand then digitize it, I would first provide you with some rough sketches for you to approve of then commence in on the detailing and coloring - If you initiate the chat I can send you some *watermarked* samples not available in my profile
Anyway, I could start working on this right now, just let me know!
Cheers!
