The tweet box and profile pic isn't showing correctly

Hi,

Sorry for the delay of my answer.

It’s a problem due to your theme.
Add this code inside the textarea in the widget (or in your CSS file if you know how to do it).

.juiz_last_tweet_inside .juiz_last_tweet_item {
    float: none!important;
    background: none!important;
    padding-left: 0!important;
}

And your theme is too complexe to keep the avatar in the right. Try by put it in the left with :

.juiz_last_tweet_widget .title-frontmodule {
    display: none;
}
.juiz_last_tweet_inside span.user_avatar {
    float: left;
    margin-left: 5px;
    margin-right: 0;
}
.juiz_last_tweet_inside span.user_avatar {
    right: 10px;
    top: -4px;
}

Have a nice day.
