This is not an easy task. Importing images to make into patterns is hard even with a high quality image. This is not from looking at it. Whether it started that way or uploaded that way...it takes some practice, patience, and skill to make this into a good carving pattern. The tools are there. People are learning. Kudos to those that make the effort. You will only get better.
OP...did you look in the PatternDepot for an already made pattern? Or the pattern sharing file (wish I had easier access to the link). Remember it assigns depth based on gray scale. The highlights in this image makes it difficult. Find a better starting point, if able. Even outline or silhouette is better.
