Are you sure? If not, I completely understand and I would just say what I have to any other artist that wasn't ok with it, and that is "then just make it the largest you are comfortable with :)"
Well, I didn't actually have a pose in mind yet since I wanted to first see if there was going to be any problems with the character. But I would be good with letting you decide. Do you have any ideas? Cause I can let you know if I like the sound of one or something. Thanks :)
