Honestly, seeing this my first response is "pfft, n00b".
Bragging is fine, so long as you have the spectacle to back it up. The only people who get away with big claims are the people good enough to make them ^^ Until you can get away with the big claims, avoid them, be conservative. If you're game really is going to be all that, then don't tell us, show us. Remember, view everybody as a cynical !@#$% who expects you to fail in a spectacular manner. You have to show you can prove them wrong.
For the love of god
It gets in the way of actually reading the text, so I'd suggest avoiding it ^.^ The same goes for the completely pointless coloured text. I had to highlight the yellow just to read it. It's annoying.
Actually tell people what you're working on, explain things. Sum up the story, talk about gameplay features you plan to include/have already made. Mock-ups, designs, anything to convince us you may actually be able to pull it off, to stop us cynics from...well, being cynical. If you don't want to spoil anything you can always write it like the back of a game case,
"Hyrule is in danger, a new unknown threat has emerged and Princess Zelda has commanded the hero, Link, to fufil an ancient write of passage, gather the lost pieces of the Rod of Seasons, and fufil the Oath of Seasons."
Something like that is better than nothing, because "HAI GAIS U HAVE A GREAT GAEM ID3A!!!111" doesn't cut it (I'm exaggerating but you get the idea) =P A screenshot or two, even if they're just mock-ups, is always nice. And obviously always announce mock-ups as such, and not real screenshots.
As for your screenshot, the resolution is *weird*, people expect certain resolutions and breaking the norm either goes spectacularly wrong or spectacularly right. The actual graphics are nice but I could throw something like that together in paint (since the graphics are just ripped/whatever). The lack of anything before to disuade my inherent cynicism definitely doesn't help.
