The original JPG for this one has photoshop effects which cannot be replicated in the vector format. So the artist has used bitmap effects to to give the image a softer look, and to make it look closer to the original. Note that all the small detail has been done in Illustrator by hand, and this type of design will cost more than the standard $14 (we always quote you if the price will be higher than standard, and wait for your approval before proceeding).
If you need something with about as much detail vectorized, you should always get a quote and opinion first before proceeding.
