SEO work on websites so I can tell you that it is not at all unusual to not see ShotCritic scoring well yet. It takes a certain amount of ramp time and link building to get onto the first page. But in six months, I suspect it will be on the first page with no optimization at all. Already the Title tag is working for this because it gets seeded from the titles of each post in the forums. But it is way too short of time for it to be scoring very well yet. And the real key to first page positioning anymore is to have sufficient incoming links (with appropriate keywords in the linking text) from larger sites. That takes time. The importance of the description and keyword metatags is very very low nowadays. Google doesn't even index the keyword tag anymore as far as we can tell from the latest research. The Title tag is quite important, as are Header tags (h1, h2, etc). Also Alt tags are indexed. All of the photos of ShotCritic have Alt tags with keywords, so that is a plus.
But actually, there are some key words that will put ShotCritic #1 in Google right now. For example when I searched for "fast dof fixes in photoshop" ShotCritic is the #1 listing:
