I've got one: Stop double posting. Use the Edit button, thats what its there for.
EDIT:
Okay, I checked the site, it--the layout--isn't as bad on a regular full screen monitor as it is on "widescreen" (I hate widescreen, ugh!)
Anyway, the background picture is lame, don't let it be a repeated picture, I dont know why but I find that very unattractive 9 out of 10 time on sites. Especially plain ones.
The specifics of your site needs to be tweaked, in my humble opinion. That part with giant letters announcing the sites under construction just screams "amateur" and not in the admirable way.
Try making a subtler graphic that announces the site is under construction and place it menu as a link back to a "Feeback" form, so that anyone who comes can leave a bit of feedback or advice for you on the matter.
Also, I'm going to just say it, but I hate the sites name. Homage or not to gbatemp, I feel that 'dstemp' is just weak. You can take that bit as you like it, I'm not trying to hurt your feelings, or even tell you to change it, I'm going to let you know that if I stumbled across your site and noticed the name, I'd laugh, roll my eyes, and say "Puh-lease. Wannabe." and hit the back button on my browser. I just would, and I feel that most people who see your site--if they've ever seen this one--wont appreciate you "Eating from GBAtemps plate", so to speak, even if they do understand its supposed to be to honor GBAtemp.
And your reviews--I didn't read it all--but they seem good, but I highly recommend adding links to the "Contents" portion so that people can easily skip to the portions that they want to read, and I think that the formatting--or lack there of, in your reviews is a bad thing.
INSERT EDIT:
Also, I think your site needs a logo, to make it memorable and all to really stand out.
And I recommend you use Video Reviews along side your text ones, as GBAtemps pretty "famous" for their in-depth text reviews so you've gotta do something they don't already have. Use effects and background music to make yours stand out from the other youtube Video Review--it'll really help. And be personable in your videos if you do make any, as personality counts also.
Okay, thats my two cents on the matter, do what you can with it, or else leave it where it stands, thats all I can say about it.
