OK, it's a nice sentiment and all.
I'll probably get accused of being racist or some other stupid shit, but here goes - there are three glaring errors here.
1. In the top, there's a picture of a black man, presumably Mr. Overton. In the bottom, there's a portrait of someone on a stand, presumably the dearly departed, and that person is white.
2. In the top, it states that Mr. Overton was in the Army. In the bottom picture the Marines are conducting the funeral. This does not happen IRL. The Army takes care of their own and the Marines take care of their own.
3. The bottom picture is obviously from a video game or something equally as inane. Your goal may have been to honor Mr. Overton, but the bottom picture wasn't necessary at all and actually detracts from your purpose. You could have made a great meme with just the top half. Sometimes less is more.
