Tattoo Tullahoma Tattoos: Parlors, Artists, Tullahoma Tattoo Shops

I got this Dragon last year while working in Yokohama.An artist at Horiyoshi III 's shop did the work.I did not want any color or a "Fantail".Shoul I get it colored or leave it as is? Does it look ok in black and gray?

I got this tattoo exactly one year ago today in memory of my 37 year old brother who passed away in Portage Indiana. The picture I submitted is a picture the artist Tattoo Tom From Shelbyville, TN used. What do you guys think? Does the tattoo resemble the picture? Do you think anything can be done to impove it? Any Comments would be appreciated.
