Thanks for the suggesting on what key words to use! Yeah, here in Chicago we have tons of tattoo shops and tattoo artists, I already looked through bunch of portfolios (that are on the web). Ironically, most of the images in the portfolios that I have seen are all done with darker themes and they tend to fill with ink every single inch of the area. It is not my intention to offend anyone and it is just an opinion of a newbie, but I sort of get the feeling that most of the tattoos in Chicago are done through two steps :
1) cover entire area with ink (as a background)
2) work with that background and create some images out of it.
so the result is: many tattoos appear as a huge splatter of paint, dull, and all 'grey-scaled to a single major color' and then you have to spend 10 minutes trying to figure what the actual art on it is.
this is definitely not the case here - you see details right away and everything is in focus etc
