I find too much duplicate content lifted from other sites. I would suggest if you are making so much efforts to copy the contents, why not take more effort to put in some original content.
As for me i think the contents are okay and the blog has a good design. The blog outlook itself is not complicated. Just try to work on what wisdomtool posted
If you want to make site look good then content is a king add unique content and add some nice quality images for your site.
Your site is simple looking as its information site you should add more pictures to your site so it will look better
