How can I ranked up my website

May be there is a problem with your keywords selection.You choose the keywords according to your services and then do promotion of your website.
Also use social media.

The number of your backlinks is very high compared to the scores your backlink profile gets. That indicates that most of the links are of low value. Indeed there's a lot of links from blog comments and such.

For example, that Wikipedia link is from a profile page that doesn't seem to be linked from Wikipedia's site. That's a "Wikipedia link" only technically, and worthless as a backlink. You need the backlinking sub page linked from the main site, and preferably from a prominent page. So-called web 2.0 sites are often equally worthless for the same reason, and social bookmarking or directories aren't much better.

If you can't clearly see how the link juice flows to the backlinking page it's very likely that you're betting on a dead horse. Even if there's a connection to an authority page you need to take an account how many other links are diluting the juice. And most of those links are nofollow...

Have you checked Google Webmaster Tools? No warnings about unnatural link profile?

I wont touch the on-site SEO, but I'd suggest you limit the number of text colours you use. Doesn't look professional or trustworthy.

There can be many reasons to be on the top position of the Google SERP. It’s not just that you have made some quality backlinks, so your site will rank on top position. Google take more than 200 criteria to rank any site in SERP. The site domain age, its authority also plays a major factor in ranking of any site.

Analyze you competitors first and try to find out that how many quality links they have.Make a proper strategy because you have to build back-links with in proper ration otherwise Google will raise a red flag.

1. I think you should really think about your keyword selection. Is that a "buyer" keyword? I looked at the google results, and half of them are just information links about what "clipping path" even is and how to do it in photoshop, and basically 2 companies that do what you do.

Are people really using that keyword to BUY services? by the time one knows what clipping path even is, chances are they already are a graphic designer and have the tools or skills to do that. People googling that keyword probably aren't people looking to buy services.

2. Get someone who speaks English to rewrite your page(s) if you want customers who speak English. Your page fails on a lot of levels regarding readability. I don't know how much Google uses that quality to rank a page, but as someone who would come to your site as a buyer - I would run away from your page.

"We are randomly committed to provide with the best services in Photo Background Remove"

Seriously? What the HELL is that? Randomly committed? Did you spin that or something?

3. Just about everything on your page is copied right from the first result. Get unique.

Haven't been to your page after some said it didn't look "trustworthy" but it sounds like you are doing some old school, color-by-numbers Grey Hat SEO. The exact type of thing Google actively works against. I'd focus on unique, READABLE content for now -- preferably from a native English speaker.

Now a days after several updates, links with quality has has far more weightage than more low quality links.. Could you share with us PR's of the links that you have created?

or there could be a possibility that your site is penalized...

You need to find related sites in your niche to capture those essential links back to the site.

Write one killer tutorial with a word count of about 2,000 minimum (forget keyword), add plenty of quality screenshots and link to at least 7 authority pages in your niche, preferably blogs with a following of other tutorial sites. Email those sites and let them know that you have mentioned them in this epic post.

When sites link back, you will taste the sweetness as your site ranks. Simple.
