Hallo my name is Berit Johanne lystad, and am a illustrator form Norway.
I saw your project description and I place a bid with high hopes.
For your drawing I'd would rather make it in illustrator. Because in illustrator you can scale it to any size you want, end it will still be good, the you can not in Photoshop without ruin the image. Also, I think that the lines/edges becomes better in illustrator.
Tracing drawings is something I do a lot of, I do trace many of my own drawings in to illustrator.
I will guarantee you that my work is a 100% self made, and if there is a problem I fixit as fast as I can.
Yours faithfully.
