What can I do to increase this page's rank

[webfeatseo]

I have this page that is doing alright for the phrase

"skyward sword walkthrough"

I used to be ranked number 2 but it has dropped

http://legendzelda.net/skyward-sword-walkthrough/

Sites like IGN are huge so I do not blame them for overpassing my rank but zelda informer I feel like I should be outranking at least.

I have a fairly good on page ranking grade using the seomoz tool.

And the OSE shows I have 11 domains linking - most with some kind of variation to that keyword. And I have actually built out more since then. Most the links are on highly relevant pages. I contacted a lot of gaming sites before this game was released and asked for a link back in exchange for a variety of things (shoutouts mostly - no paid links)

The page performed extremely well when Skyward Sword came out and I got hundreds of thousands of hits but as my rank is beginning to drop its a lot less (also can be attributed to hype dying down).

But any suggestions or glaring issues would be great. Link building is something I am always doing as well - mostly through guest blogging.

Are your rivals outpacing you in quality inbound links over time? It would appear that way as the #1 SERP http://www.zeldadungeon.ne has a PA of 70 ( root domains links) and while http://www.zeldainformer.com/16-skyward-sword/walkthrough.html has PA 39 ( 4 root domains 318 links) its DA is much higher than yours with 708 linking root domains vs, your 125.

Also compare your page's Page Speed score with your competitors and see if you can improve it's load time (you score an 82/100) https://developers.google.com/pagespeed/.

Also I think your title could be improved with some branding -
Skyward Sword Walkthrough | Legend Zelda Net
Also change out the images for H tags in the page headers

I was thinking it may have to do with domain authority but was hoping to outrank despite that.

My site is hardly more than 2 years old while zelda dungeon is more than 10. Zelda informer is at least 5. And IGN is even older. So I have put a fairly good dent into a lot of their keywords and will hopefully be able to do even more over the years.

And what images for h tags are you referring to?

[legalseo]

Your H1 is coded to render as an image (in Firefox, not so in Chrome ) but I don't know how well the bots read this kind of code - here's what I pull from your source code for your H1 tag::
<div class="uscontinue">

<div id="post-3126" class="post"><div class="ptitle"><h1><cufon class="cufon cufon-canvas" alt="Skyward " style="width: 125px; height: 38px;"><cufon class="cufon cufon-canvas" alt="Sword " style="width: 93px; height: 38px;"><cufon class="cufon cufon-canvas" alt="Walkthrough" style="width: 176px; height: 38px;"><canvas width="192" height="38" style="width: 192px; height: 38px; top: 1px; left: -1px;">canvas><cufontext>Walkthroughcufontext>cufon>h1>div>

here's what I would expect (and the bots as well!):

Skyward Sword Walkthrough

Yea I use the cufon replace thing. SEOMOZ picks it up as a h1 with the right text.

I would like to get more feedback on this though if anybody knows the effect of cufon on seo
