First of All,You should change that big size logo to medium size and the important thing for visitors on your site is, the content so,you should make the text font style bold or attractive like news paper writing so change the font style and also try an other other simple white background theme of site or place the widgets on right side they looks awkward on left side.
your first blog, with simple template this blog loaded faster, great second blog, i think place ads at match place... generally, because i like simple blog with high quality content i think your blog is good but you should to set more interest with change font on content so not same with sidebar or header...
It looks like you have duplicate content all over your blog. It is useless if you copy and post contents on your site from other websites. Please consider writing your own unique content so they are worth reading. Get your own hosting account and domain name so your hard works wont go anywhere.
