Those sites do have quite a bit of "sameness" to them. One big thing you can do is start varying your fonts. The fonts on all the sites are pretty much the same. Start adding background colors to your table cells that are different from the background color but work with it. Also, quite a few of your background/text color combos are hard on the eyes. Light backgrounds work best with dark text, dark with light text. If the shades of text are similar to the background colors it makes the text very hard to read and thus makes the site very difficult to review
Also, find a few more sponsor sites to promote and rotate niches. That will help both your conversions as well as your ability to get listed. Submitting to Tranny day after day after day will start getting your sites declined simply because no LL owner will fill up an entire category with one submitter's sites
