Sonshu, I am honestly impressed..!! Your blog NO way says that it belongs to a 14 old.
Few suggestions:
1) You can make labels in 'cloud' format. Right now it is very lengthy.
2) Would be great if you can increase the font size by a pixel or two (it appears too small for me, I do not know if it is my browser issue :))
3) You can push secondary items (i see lot of badges) towards bottom of side bar and bring blog archives, popular posts etc to top. This would help reads to have an overall idea of the topics and choose it.
4) I don't see RSS feed anywhere in the side bar. Wouls be great if you can add it. Many people use RSS readers to subscribe.
Keep blogging.
