All right, I can't see the one belonging to LuigiPenguin. Looks like it's down or something.
You might wanna check that so the rest of us can give you some more advice.
As for that SuperSmash one, well, it needs a lot of work.
I think for starters, the title of the page (what shows at the top of your browser) needs to be punctuated properly.
Currently it's "HOME - super smash"
You might wanna change it to something like "Super Smash Bros."
Also, it's pretty strange how your site is supposed to be a flash game website, yet you focus really hard and are so biased towards that one Super Smash Bros. Flash game.
You might wanna change the background, too. Tiled images really don't usually look good.
And again, back to punctuation.
A good website's sections at the top would be punctuated properly.
You might want to pay attention to how it says "HOME - games - Music/ videos - funny pics - talk to me"
You should probably go ahead and change them to "Home - Games - Media - Gags (or whatever synonym you can find) - Contact"
And again, more onto punctuation with the labelling of your games in the games page.
Also, I'm aware that you're 11. I think you should probably be warned that pretty much all of the music on your music/videos page is illegal. I don't want you ending up in trouble at some point, so just watch out. I mean as far as I know, unless you have a license from each artist to use their music on your site (which costs a lot; don't even think about it) or you're embedding a YouTube video of their VEVO, then you can't really have commercial music on there.
There's a lot more on my mind, but I don't want to trouble you. I think these are the most important ones right now, so you should get to these first.
Hope I helped.
