At the start of the ball scene, shortly before the "One's consequence varies so much" line, a gentleman passing by gives an admiring glance in Fanny's direction, and she turns her face away, shyly but smiling. That'll be Fanny saw that she was approved; and the consciousness of looking well made her look still better (ch28), I suppose. :-)

The other is a biggie, in my opinion. Do you remember what's in Tom Bertram's self-portrait? Just himself and his easel, right? When Mrs Norris calls it "very modern, very modern", she's just saying that it's a bit avant-garde to paint a self-portrait using a mirror, right? Not quite! The day before yesterday, for the first time, I glanced at the other side of the painting and was rewarded with the sight of the grim reaper (or some such black-robed spectral figure) standing with a hand on Tom's shoulder. I find this interesting because it makes him more fanciful and less of a representational artist, and tips the scales toward a more metaphorical interpretation of his sketches from Antigua. It weakens the accusations against 'Our Neighbours' and Sir Thomas. It doesn't dispel them, though, what with there being no smoke without fire and all. I still think Tom had some basis for saying "What, and do as you do? Even I have principles, sir." But it's adequately explained by a general objection to slavery on Tom's part combined with a fanciful artistic streak, without any more particular censure of his father.
