I have never worked on illustration, but I am drawing a picture in the scope of my hobbies. Since I have a job, I can not respond to a short delivery date, but I will reply within 24 hours. People are good at it, the background is not practicing so well because it is practicing (but it can be drawn if it is simple) I think that if it is an illustration that does not need much drawing, it will be a month as a guideline. Please feel free to contact us. Also, it will be a great help if you mention the character designation and features.
