I made a concept picture of realistic Jek 14.
I uploaded the picture here rather than Wookiepedia because Jek 14 is only on a LEGO (Star Wars) show. I don't know if there are any copyright things to worry about, so if there are, please let me know. I used this image as a base, and I used several other images for different parts of the picture.
Leave a comment letting me know what you think.
