I am Sarpras Navas, Webmaster of two article directory http://www.kokkada.com and http://www.articles2u.com. I will request you to review my two article website and post your valuable comments.
When I first saw the title of the post I thought it had just two articles. So, first thing, try to be more descriptive with them, within your directories. Both directories are very similar and would be great to have a section "Most Popular" in the first screen or so. You also have space for another add.
Look very plain and almost exactly the same. I have seen several like this one, were they made by someone selling their service? There is way too much white. This is a tough market to break into because their are people selling these directories like hotcakes. I suggest doing some changing to make yours different and unique and then market the heck out of one of them to compete in the market. Two almost the same seems useless to me but I wish you good luck.
First & Second Try adding more red around the layout, it looks too plain and lacking colors. Also: a nice logo design (not blue.. maybe maroon or red) would make the site look much better too.
