Dear client, I'm Hossam (Photoshop Expert) and I'm ready to start right now ...
I've seen the photo you've attached of your son and noticed the dark circles you've mentioned as well ... The all 4 photos looks great except his eyes need to add white so it can look natural and I can do it for you
Please send me the one of the photos with higher quality so I can give you a free sample to prove that I understand what do you want exactly and to prove my capability of doing it
Price depends on how many photos you want to edit
It'd be nice to disucss details with you so, please don't hesitate to ask me about anything
Thanks for taking the time to read my proposal, waiting for your reply
Best regards,
Hossam Elshall
