Or, in other words, why “DO YOUR BEST” will never ever work for providing proper instructions.
1. Understanding of “best” or “perfect” or “beautiful” is not the same for each person. My vision may differ from yours.
2. If I do my best for each image, I will rate the project accordingly. As by “the best” I mean the deepest retouch of highest quality, it will take more time and efforts to edit your image. Therefore, it will cost more.
3. As you are not giving any particular directions, each and every further amendment / revision will be charged.
Additional instructions or extra revisions are charged separately. Additional instructions are any instruction you have not mentioned (forgot to mention) while placing an order.
And as you have not provided any proper instructions while placing an order, each further instruction will be considered as additional.
