I don't feel like I was specific enough in my last post, so let's take a look at one of your screenies.
I've circled in pink the objects in the image that draw the eye's attention. There's seven of them. You want one of them.
What are you trying to show us with this picture? The base in the bottom right? The temple-looking thing in the center right? The Panthers driving on the bottom left? The flurry of missiles? The planes flying? It's unclear.
This is called the
subject of the picture. Your picture should have one, or at most two, subjects. The mass of screenshots you've been so nice as to provide us with have no clear subjects. This needs to change if you want people to respect your work rather than laugh at it.
You have image-editing programs available - use them! In that picture above, let's say that you wanted us to see the faraway battle. Crop out the base in the bottom right, and the tanks in the bottom left, and the thing in the center right - they are only distractions and do not add to the picture.
The more things that are happening in the picture, the worse the picture is.
