This is a nice art, Sander, these two creatures are looking so fondly to each other, as if they've been best friends for a long time and these days they could even understand each other without even speaking words anymore XD.
I love all the little details too, you certainly have put a lot of works into creating this illustration ^_^.
Well they had set up the whole factory so I think they kind of bonded that way so I guess you're right :). I believe there are rumors they could communicate today without really speaking but with nasty sounds and evil laughs :D
Thank you very much @scrawly! :)
