How to become a Tumblr girl?

My question was deleted.So, I'm gonna ask this question & hope it doesn't get Deleted. I'm a really big fan of tumblr girls & I really wanna be one. I'm 14, skinny, short & brown hair, green eyes, long legs, and small b**bs. I have done my make-up perfect, wore really cute outfits and everything else a Tumblr girl would do. But, everytime I'm ready to take the picture, I Look like a mess! My hair looks frizzy at the ends, my chin looks just werid, and my forehead always look scrunched up & ugly. Then, there's my smile. See I have to take photos with my Iphone 3gs so, I can't see myself. Right when I think I found a great smile (cause I guess it just makes me feel pretty), Its not pretty at all! It looks as if I have something wrong with my face! (I don't btw) Does anybody have any tips on how to improve The info i've given you so far? Thanks in advance!

Here the link to what I use to look like;My hairs not blonde anymore, It's brown and Almost resting on my shoulder but not quite. Thanks agian guys!

Most tumblr girls have a professional camera and photoshop. They'll deny the *** out of it (I'm on tumblr, I know) but many of their pictures are shopped (hair lengthening, teeth whitening, fixing their eye color, adding effects to the background) it's subtle, but it looks cool. You can try all you want, and get noticed that way. Try to do pic for pic or other things like that, if you have other friends on tumblr see if you can feature eachother, that way you can find new followers. It's not an overnight process either.
