3 months later: Please review my site

Hello fellow warriors.
I haven't been here for some time because I was working on my site and doing my regular job, living life etc.

Anyway by the beginning of March I started my first website - internet marketing experiment. My goal was and still is the same - I don't want to become rich or have a big income - I want to learn how to attract people to my website, to learn marketing skills.

My goal when I started was this:
- 50 unique visitors/day
- 2 user registrations/week
- income $1/day from Adsense/Affil marketing...

You can read about my beginning in this thread. Since then I have completely redesigned the site because the old one was ugly and cluttered.

The site is: Film Screenshot Quiz

Now I have very clean design, Facebook login and few more tweaks here and there.
I used to have on-site store promoting ClickBank and Plimus products but I no longer use it - it felt sort of forced.
I still have AdSense which I hoped would make few cents a day but it has made me one dollar in three months (you can laugh now). Instead, I replaced CB with Amazon Associates and I incorporate affil links into my posts.

My Google Analytics data are:
- over 1000 unique visitors (around 350/month) = this translates to 7 uniques/day, far from 50 that I envisioned
- 3350 pageviews, 1600 visits
- my bounce rate is huge = almost 70 percent

I used to have new registrations almost every day for first month but those people didn't participate or were spammers. Actually only one guy is active and he's been great - I just envisioned more people competing.
And as for sales - there's been none and just a few clicks on Amazon links.

I have tried:
- Adsense campaign twice = didn't bring any new registrations but made up all those clicks, too expensive for me
- Paid tweeting/Facebook likes = practically worthless
- Paid backlinking strategy (quite expensive) which proved to be somewhat successful. It was linking on blog network for $40. It skyrocketed me on first page of Google on few keywords but as I don't have any other backlinking plan, it lasted only few days. In that time I saw double/triple increase in visitors - few registrations, no clicks, no sales.

I suspect where my weaknesses are:
- I don't do enough backlinking: I use competition directories (5-6 sites) that bring some people to the site, rest is Facebook, mailing list or Google
- I don't have text content. As you can see, my page is built around images which isn't really friendly with Google. I changed my strategy and now I accompany some of my image posts with information/reviews/thoughts and I also write 2-3 articles per month.
- my Unique Selling Proposition is kinda hard to sell. There are some sites out there that do the thing I do but I'm the only one who gives away cash and prizes. But is that enough?


So my question is: What should I do next? How can I fulfill my goals?
