Yeah. I agree with Ujjwal. Here are a couple of pointers though
Work out a good colour scheme, and use the same theme throughout the site. You do have a colour theme already, but i suggest you make a few changes to increase readability.
If you have several sections on a single page, make sure they have enough text to support them, otherwise the page would look very empty.
If you're using images from elsewhere, make sure that the original background of the image doesn't show in your pages (i.e, if the image was taken from asite with a white background, in most cases, the image will have a white background as well)
And most importantly, never upload your picture to a site which could be viewed by strangers. Tis not a good idea. More importantly, with the kinds of guides you seem to write, it's advisable that you provide no photographs of yourself that could help someone track you down
