Greetings
Actually not bad for starting out...the only thing that I would say of concern is the width of your site with some link sites. There are some out there with strict guidelines on making sure your site will load without scrolling to the side in an 800 wide window (for this you want it to be up to 770 px wide at most). So this is one thing to consider with your current and new sites.
The other is the image on this one site that I am assuming is a well over enlarged image or were you purposely going for that look? Some link sites, again, will look at this and some will say nope...
The other thing I would strongly suggest is to make sure you put all your keywords, description tags, and name your links and make sure you use ALT tags. Even though not all search engines really focus on these much anymore, there are still some that do...yahoo does. You definitely want to focus on search engine traffic as well. Also, when you do your recip tables, try to balance the big name traffic link sites with the smaller ones across your mirrors. I won't go into the details here or on much more because Im saving my typing fingers for new webmaster tutorials which will be at my directory (see my sig below)
Anyways, I look forward to more of your sites, and just to pass on a valuable piece of info, if you are getting into free gallery sites, I have the perfect option for you if you are interested? If so, Private Message me here for details. I may run a link directory, but one of my jobs with this is to help webmasters with their traffic and to make potential sales (which is important ...lol...)
Cheers
