The little phone emoji is too small to be really visible and so looks just like a black blog. I would toss it.

No need for the checkbox either. Note the comma or whatever it is hanging out on its own line.

I would put Edit/Annotate/Re-size on one line, UNLIMITED IMAGE STORAGE on another line

Photo analysis, not photos analysis

Customers/Partners or Customer/Partner -- just be consistent

Not sure what you are saying in the section called Images from/for Contacts...

Your customers/partners can create a case - or any other object - from Images directly from their device without access to Salesforce. (That much I understand...) What do you mean by (using SharinPix Component to Capture Image on your website, salesforce community or mobile app)
... They have to have the component on their phone? I think that is too much info...Let them ask you how you can to this.

1. because of image size? (not images)
2. you mean Field Service Mobile App/Salesforce Mobile APP?? How about Use images to empower both the Salesforce and the Field Service Mobile Apps.
3. Keep your bullet points in parallel construction with active verbs: Upload, Select, Edit, Leverage and Fill your Salesforce fields OR
   Use the image recognition power of Einstein to fill your Salesforce fields.

1. advice not advices
2. Note the verbs: Adds image features, should be integrates with -- leave out the "every" -- it breaks the parallel.
3. Our advanced features include
4. How about: Our integration with Einstein expertly delivers image recognition you can use.
5. ...our team is made up of image experts, photo addicts and picture lovers. -- There's really no need for capitalizing these.

Addiing the 2017 version of various articles makes it look like you haven't really updated a Full Setup and User Guides recently, which means the customer will have to go back and forth to get the full information. It looks kind of sloppy and unprofessional.

Also with the same theme: You have Use SharinPix Lightning Components to build a new image experience for Salesforce desktop and mobile AND you have "How to use SharinPix Main components interface." Seems like these two articles should actually be ONE article, no? Again, I don't like the way it makes you look.
