@DBNewbie:
Nice
screenshot 
hehe...
Seriously though - it does get tiring when people say "COME SEE MY SITE!!! I'VE MADE A BANNER AND THEN IS A SCREENSHOT OF A CIRCLE!" or variants of that.
Also - from a design point, the rule I go by is: "If I went to this site would I go back to it regularly? Do
I like the look of this site?"
Basically, take a 3rd person point of view on it. "Its not your site - someone else made it, do you like it?" kind of thing.
Personally, its too much... too busy... Lose the DBP Packaging - too distracting. Do you get a choice where to put the google adds? If so - bung them at the bottom. Make the banner smaller - on my parents screen (1152x854) I get less than half the vertical space actually used for content. There is nothing on the models page. On the screenshots page, lose the [ i m g ] tags (had to put in spaces to allow the forum tag to show). Also try to make it clearer what you're doing. On the source code page, try bunging in some <PRE> tags around the code.
Also - and this is something I say to all beginer web"desgieners" - google for sites which teach you the good and the bad things about web design. Some sites (the good ones) actually give links and examples of bad sites and, most importantly, WHY they're bad.
I like the rule: "subtle". When you look at the colors, I always try to avoid colours which are fully saturated.
Do you use firefox? If so - get the ColorZilla Extension and the Web Designer extension. They add LOTS of usefull things - like realtime CSS editing, etc...
Finally - ignore the people who just insult without help... But also listen to them
They make a valid point. If you tell someone to go to your site and give their opinion - beware... some people might actually be honest with you. In its current state, your site looks like it was made by someone who is learning how to use HTML for the first time. If this is the case - dont ask for a review! That'd be like someone asking you to review a Hello World app!!
Finally Part 2:
http://www.w3schools.com - simply the best site for learning HTML/CSS/Javascript and pretty much anything else web related.
