If you have a sec, would like some feedback

this is just a basic wordpress theme right now , as you can see. I want a theme more appropriate to the subject, one that can have comments,etc.

this is one that I paid to have done, but generates no income ..

it is fed with comments continually , would like to know how ?

also the theme for this one is the main question at present, would appreciate any advice, will pay if necessary.
thanks guys and gals!
