It's great that you started blogging about J-dramas and other stuff! I visited your page and the header looks solid. I think you dislike the general look of the blog because there's no background at all. I think that the header could be extended in order to serve as an image covering the whole page. You might also want to consider choosing a different blogger template so that you could categorize the reviews more easily. However, it all comes down to your preference. You need to play with the settings in order to work out what's best for you :) I hope some of this helps.
Yeah, I was also thinking extending it will look better. The thing is choosing template is very time consuming, but yeah I think I need to choose a new one. Are downloadable templates good? cause my worry is it may break the blog in the long run.
