The cast on edge does look pretty loopy, but the stitches on your rows don't look too bad. An even tension will develop the more knitting you do, so don't worry about that for now, you'll get there. It does look like you're adding stitches, so make sure you're not put the yarn around the needle between stitches, and at the beginning of the row hold the yarn out to the side a little bit before you make the first stitch. If the yarn is up over the needle to the back it pulls up the first stitch and the 2 legs of it look like separate sttiches.
