These are very impressive, especially considering they've been drawing without reference. I would say that area to improve on is with variation of shape. You have a tendency to curve and round off features where some straighter lines would give more character / realism. For instance, your jaw lines all follow a similar curve - some variation would add character. Very nice work and I look forward to seeing more. I had a look at your DeviantArt gallery and am now following you there too :-)
