I want to develop an application to automate the whole process of photo shoots. 

This is the process I need help with and I need to know if it is feasible with Zoho Creator:

I take photos > I pass it to postproduction > the postproduction guys receive it > and once finished the postproduction sends it to the customer to validate the photos taken. 

This last step I was thinking in 'Customer Portal' and add like a 'likes' system to validate the photos, if they don't like a photo, add a comment and it goes back to postproduction to be reviewed.

I need someone to guide me to know what are the steps to get this done with Zoho Creator, as this part I'm a bit lost. 

Thank you very much!
