You could just add custom css, e.g:
.sprintrFeedbackNode {
left: 0px;
}
In addition to Fabian's answer you can also add
top: X%; (Where X is a numeric value, default 25)
And if you want to rotate the feedback text, you'll have to use the transform function:
transform: rotate(180deg);
-webkit-transform: rotate(180deg);
-ms-transform: rotate(180deg);
-moz-transform: rotate(180deg);
