Poker Rats

We are looking for a dark cartoon style that resembles the famous dogs playing poker art but replacing the dogs with Rats all having a different themes to them. Our friend group resembled our selfs with different themed rats. We have a King Rat (Rich and loved), Reaper Rat (Grim Reaper), Hood Rat (Gangster), Mad Rat (Crazy/Mad), and Billy Rat (Hill Billy/Farmer). We have a rough sketch but want it to look more detailed and dark with a cartoon style with all of them around a poker table playing poker. Our sketch is a very general idea of the characters style but want them places in the Dogs Playing Poker portrait. Let me know if this is possible. Thank you!
