Sidebar content not centered

Hello Support,

http://ps.bypundyk.com/the-shot/
I have added the css code below so that the sidebar background color works. I have added an image and text on the sidebar but it does not center as you can see.

Hope you can help find a solution to my problem.

.sidebar {
background: #ccc;
min-height: 600px;
}
.gravatar {
border-radius: 0;
}
.comment-count {
border-radius: 0;
}
.rounded-container, .rounded-container img {
border-radius: 0;
}

Thanks,
MP
