Lol.. you're better than before kons but still need improvement..
1st.. background needs work.. looks like you got a large render.. duplicated it a couple of times and blurred it abit :?.. the text needs work too.. 5.5/10
2nd.. nice background.. this looks like you have used either a C4D or a stock background.. but you completely ruined it with the render.. it doesn't fit well and your text needs work.. 5.5/10
3rd & 4th.. I'm doing both together coz they're basically the same.. the background again needs work.. don't make it black and white.. doesn't look good.. text also needs work.. the light source has to have something around it or with it.. don't just put it alone. 5.5/10
6th.. the background is too plain.. text needs work.. 5.5/10
7th.. it's ok.. better than the rest..but that filter.. can't remember the name but it's used only in a few occasions.. it's not good.. try using the blending modes too.. 6/10
Just try harder and follow some tutorials.. but you are getting better.
