The first one's effects don't have enough contrast to blend with the focal. As for the second, it had potential, but it's blended way more then needed. You should use gradient maps and other effects to color it. And the text, not needed.
The second one really could be awesome. You need to learn to use contrast in your tags. Try some gradient maps/photo filters and try to integrate some effect c4ds in to make it look more dynamic.
Your depth and lighting sucks balls. Work on it faggot.
