Hey there!
For scalable, you'll want this done in vector. I assume the attached is a mockup of the elements you want included and of the layout, but that you want it done in a different style. Could you provide references of the style, level of detail you are looking for? My process would be to do this by hand then vectorize 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!
