The blog looks too generic.. I've seen this template many times before. Try getting a custom header designed. ALSO: the content is looking great
The Blog is Good, Simple and upto the mark, the content is good, you may try some variations with the header part
The design is clean and this blog might become an interesting one later, but it should be different from the other ones both in the content and the design in order to stand out from the other blogs and to get its own visitors.
