It's not bad; it seems like an average blogger's blog.
One thing you might want to consider is screen width compatbility - I have a 1024 by 768 resolution right now, and I dunno if the width of your blog is dynamic or not, but the first image of the first blog post I see has an image that goes outside of the column bounds.
I, too, have a 1024x768 screen resolution, and the picture is greater than the width of the table. I like the blog design and the logo looks nice. The load time is good. You have quite interesting stuff. I started looking around. You cover a wide range of stuff, which seems good.
I agree with both repliers here. I like the color scheme, not very distracting. The image on the top post is a bit unaligned with the content box (1024x768 resolution).
Cool.... It looks like a decent blog.As others said align your first image properly.And your right column is having quite a lot of white space.
Good Luck
