I think in general having that 'welcome' image is a big mistake - that's a Genesis Diamond before its two redesigns and isn't really indicative of the beauty KittyCatS has to offer in whole in 2013, it seems like a good idea for early 2011 during KC's opening but we're so far past that. We have colorful kitties, tabby kitties, exotic fur kitties and eyes (among other traits) to boot! Look at the list of traits in the beginning of KittyCatS
http://goo.gl/tDkgd (most of these beginner cats are the only ones used graphically in the site design) versus the palette we have to work with now, it's time for an update on those images!
It also wouldn't hurt to have a more colorful demonstration of trait combinations even if the current site theme is kept simple (I'm a huge fan of simplicity myself and graphically, it allows for the kitties to speak for themselves in the images used versus a bold theme), I sure know it was the pink & white that got me into actually breeding KittyCatS, not the blue-eyed tabbies, and these colorful kitties aren't represented in any form in the design! There's so many people who love fantasy colors and join to acquire a pink & white, these individuals aren't enticed by the site at all even at first glance as these furs weren't around when the graphics to the site were made. Featuring solely those furs from the beginning is great but it also shows how the site hasn't been updated since to showcase the rest of these beautiful traits.
The "Welcome" picture itself could be so, so much better and is a giant turn off. An an interactive (and fun!) idea would to host a contest where community members submit their incarnations of the welcome page image (A picture contest of sorts?) and KittyCatS can select the winners that they feel best suits the main page in both picture quality and how well it represents the diversity of KittyCatS as a breedable. The final product would be the chosen winners featured on a randomized, switching slideshow of some sort as the welcome page image with the same dimensions, it'd be a great way for breeders to showcase their diverse catteries, and would cover a range of kitties and one to pique each new visitor's interest because that bland kitty on the "Welcome" page is so off-putting, even when I joined in 2011.
Reminiscing on joining KC, I remember I saw the site and it really didn't 'sell' me on wanting to partake in this breedable, I had to venture out into secondary markets and see the beautiful in-world cats to see just what KC is all about visually with the range of furs and colors, some which fail to be highlighted at all in the current site design. I assume the site design hasn't been updated since KC's opening by that much so I think it's time to re-vamp some graphics if not the whole layout, and potentially add more to that giant gray bar on the left like a Flickr image bar.
The more images people see of kitties and the wider the range and variety of those kitties seen, the better! And we've progressed so far since 2011 that I think in 2013 the site is more than deserving of needing of an overhaul, at least in some of the kitty graphics department like the "Welcome" page and potentially some of the banners. If a giant overhaul requires too much time and resources, at least host a contest or switch out that "Welcome" page because it's really not that welcoming and fails to show the beauty that is KittyCatS with its multitude of furs.
Maybe on the welcome image too KC could add little fun, informative facts that are enticing to know as a newcomer like "Did you know kitties can have over X possible combinations of traits!" "Kitties come in all sizes - toys, teacups, and more!" (Obviously better worded LOL) and whatnot to really let people know how diverse our breedable truly is, because that static image of the first incarnation of the Genesis Diamond really doesn't speak out in that way - make that picture dynamic and showcase the community's work, and make people feel "welcome" to just how amazing KittyCatS really is through these images, namely the "Welcome" one. This site is a first impression for plenty who are intrigued and wish to learn more - it was for me as well - and it doesn't do KittyCatS justice!
