The way the images work together is nice, though I'm not sure what narrative or argument you are trying to convey. Your text object is about Instagram, and your image object uses Instagram. But is it also saying something about Instagram? If so, I don't know what that something is. Otherwise, once you get past the grid format, there isn't much in the way of substance. Even if you are going to focus on the format over content, then you need to think about using the grid format to convey something. Otherwise it just seems gimmicky.

For revision focus on developing narrativity or argumentivity (I just made that up but I suspect you'll know what I mean).
