How to draw in a picture of a viper into a sketch

Hi guys, I am trying to figure out how I can sketch out a picture perfect drawing of a viper which I then later need to get it machined out via laser cut on a piece of sheet metal. I know you can do sketch picture feature and insert the image then trace over it but the drawing came out very bad. I want to find a way to make it look very nice in a quick way. Please let me know if this is possible? image is attached below but id like to get tips on how I can pull it off for any image with more curvy lines to them. Please any advice would be great!
