You have may have more year more logo behind you but your designs and styles are not innovating. Some of them are even too clip art or just to simple. Or you have them added stuff that make them loose the simplicity of the logo or bad font choice of some of them.
You need to get more Inspiration I think and check what is the trends at the moment. Think more about a design style and more about simplicity of a logo.
@Square. The logo that are now in squarelogo portfolio are better but we do need to see what was there before so we all could judge the same as Redrum. Cause this is quite unfair showing different things and claiming that other are wrong. Its like getting a F mark and erasing the paper and rewrite it with correct answers and ask other people what you did wrong.
This line is big bull cause there are logo in your portfolio showing the opposites. Don't need to make sweet talks here to get people thinking different.
I almost always make sure that my logos work well when printed in one solid spot color in small sizes.
