Welcome , and good to see you already have found the better taste that the Rba's can provide . If you drill out your air hole in the cover a little bit , you will get even more flavor . If you mouth hit ( draw into your mouth , and then inhale ) you might want to leave the hole , as is . If on the other hand you lung hit ( draw on it like a hooka ) then drilling out the hole will provide more throat hit , vapor , and flavor . But start out small , and go up from there . Mine are at 1/8th inch , and work great . Some go bigger than that , but 1/8th is my limit . And not quite sure what you mean by "artwork" But good luck anyway .
