Reduce free spaces

Hello,

First of all thank you for your support!

We are getting close to final of our website.

I will attache a picture where i draw some red spaces - those are the area i would like to be able to remove it or to make it less visible.

Are too many free (white) spaces - i want to make it a little more close the design. The area between a tile and the content of that module it seems to me that is too big; i want to reduce as much as i can.
Theme i used is:GAME MAGAZINE

Thank you in advance!!!

Also how can i change titles of modules not to be CAPS and no bold font.
In my picture: Recent News, Projects and Latest Tweets (no bold and no caps)

Thank you !
