Do you expect anyone to get angry because of the wing-it differences you choose? Do you try and avoid changes that might 'ruin' a picture?
No? At least not anyone reasonable they know what they’re signing up for and I am willing if something in the the picture is unacceptable to look into changing it.
And as far as the last half of the question goes. I try to be faithful to the original idea sent to me and keeping in mind what they want. So, yes?
