Hey Jonas!
Thanks for the link with the references! Could I see the picture of you you’d like me to base the illustration off? 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!
