... it has several problems.
The main was is that it is too busy. You have too many things happening for anything to stand out.
Suggestions:
1. Reduce the contrast and brighten the background so that it doesn't stand out so much.
2. Get rid of most of your text and just create a few article titles/ interesting headlines on the front. You have way too many right now.
Thanks for suggesting, I'm going to make another one now(and now for sure it can you read and not too much article)
Plus because I'm bad at graphic program, this cover i made only with paint. The headline still same, but now i won't use the elements again, but card picture. For the background, i think it will be still same (But Decreased Density to the lowest to make sure the text can be read)
