Changing header image/logo alignment

First of all, please remove everything down below that @import line from child theme stylesheet.

and then try putting this in there

#blog-title {
	margin-top: 20px;
	text-align: right;
}

@media screen and (max-width : 480px) {
	#blog-title { text-align: center; }
}

The logo image itself needs to be edited a little bit, so that the circle on the right (pink one) is close to the right edge. The best is to crop it to fit on both sides.

Your child theme stylesheet will have that standard comment block at the very top, and then 1 @import line, and then only additional CSS code to overrwrite parent’s.
