Eye Colour Alteration to Dark Grey

I am looking to have the eye colour in my photos adjusted to a natural-looking dark grey colour. This transformation should be as lifelike as possible, without any unusual or overly vibrant appearances. I require a skilled photo editor who is able to:

- Alter eye colour convincingly
- Retain the realism and texture of the eyes
- Consistently apply changes across multiple photos

Experience in portrait photo editing, specifically eye colour changes, will be highly regarded. I look forward to reviewing your proposals and working with you on this unique project.
