Link Building After Penguin

Hello everyone,

I own two art based blogs that are both a year or so old. I have been running the blogs for fun but now I want to increase my traffic and revenue. One blog is geared toward graphic design and he other is geared toward traditional and digital art.

The traditional/digital based blog currently has over 100 tutorials with very very little back-links. Now that I have the articles, what link building methods would you suggest for an artist blog?

Here are some of my ideas:

-Social Bookmarking (There are a few sites where I can add some tutorials for traditional art and write tutorials but this would be more geared toward the digital tutorials.

-Slide Share( Creating Power Point presentations and uploading them to slideshare with a back-link to the full tutorial in every slide.)

-YouTube(Doing the same thing as slide share but with youtube)

-Deviant Art( Creating tutorials with the articles and submitting them to art based sites like deviantart)

-Forum Posting (I am not sure if this is very effective)

-Combining tutorials in a certain niche and submitting them to that niche( For example anime tutorials..link build through anime sites)

-Facebook/Twitter (I do not know much about seo for either other than fb has its own search engine/groups and twitter hashtags and retweets)

-I see many people use fivver gigs but im not sure if its useful.

So, I am inexperienced at link building(since this is my second blog and seo project) and would like everyone's opinions so I can develop a link building process after each tutorial or article on the site.

Thanks in advance.
