I'd first like to thank you for your consideration. With that being said, since I have degrees in both Animation and Graphic Design, pencil sketching is simple enough.
With that being said, how detailed do you want the pencil sketch to be? Do you just want line work done, or do you want shading? Does the design have to be exact, or are liberties allowed? I would be willing to discuss it with you if you are interested. Feel free to message me with any questions or answers. Thank you for your time.
