It looks really basic, not bad but really basic. Needs more content and information. A nice logo would be a good idea too. Also, if your actually going to do something with this blog then make sure it's all in one language.
I dont see any difference from the basic theme, you should try getting an domain and get an custom theme if you want to get some visitors to it.
Oh, what do i see in header? A bluried-out flower picture? how CREATIVE. I think, beeing a good developer in some kind of alien ways means you have to be creative. So, make your own design, or better, buy a domain name and remake your site from zero, maybe hire a programmer, like me, and make a unique, good looking, modern site.
Color combinations you selected don't look very good! Website has no logo and doesn't look in professional style! Website header is not accurate and there is no footer! A lot of work should be done in the future!
i think the color theme doesn't match. i'm color blind, but i can see colors, and it's a little off. it's also plain as well. though i praise the slight attempt to make it a little graphical. jp
