Firstly, it is a little odd to have an English language website, but the title and domain name are not spelled correctly in English: "Girles" should "Girl's". It isn't clear if the blog is targetted at a particular segment - the title (kind of) suggests all girl's fashion, but the spelling and the asian look of the main piece on wedding jewellery suggest a more international bias - I think you should make it clear if you are writing about a specific area of girl's fashion - it will help your SEO, too. From a design point of view, the navigation menu on the left is too wide - the main content should have a bigger proportion of the screen area. Also, having a navigation menu across the top always looks good because it lets people quickly get an overview of what the site contains without having to scroll down a long page (most people won't bother). I'd also make the header smaller - the design is nice, but it takes available screen space away from the main content. Finally, the text in your "Popular Posts" column is "wrapped" around the images, but there isn't enough room, so it is doesn't wrap correctly - some is beside the image and some is below it, with a big gap in the middle of the text. I'd suggest (if you want to keep the images), put the text above or below the image and put some kind of divider between the items. Hope this helps.
Blue is used too much, try to experiment with different colors especially since your blog is about "FASHION".
I agree with pcuser! Better start experimenting on colors as this is a fashion site. Try silver or gold border to blend with the jewelries... Try adding header and footer in the site.
apart from the spelling is not correct, but i dont think this is an issue because if i understand it correctly you just want to use this as an adsense autoblog type site, which looks good for that sort of thing, good luck in it, it will defiantly bring some passive income
