I'm partial to the sketch most among the last three images. Whether or not it was intentional, the unfinished shading on the forehead, chin, etc. almost seems like she's missing skin, and that you're instead seeing a matrix of computer graphics where the skin should be. I know it's just my own takeaway, but I like it.
The overflowing wave in the eye is a nice metaphor, and I'm not sure if I've seen it done properly before? Even if so, this is definitely something I'd look into refining into a work beyond a sketch/paint book. You captured a strong metaphor, so I'd definitely run with it. (Unless you read it differently; the way I see it is that tears are the overflow from the worlds captive inside us...which is nice and comforting, especially for writers and artists.)
With the Chi Square image, my only complaint is that the cups are not proportional to the table, or vice-versa. Otherwise it's pleasing to the eyes. The colors blend well, the writing isn't...entirely off-putting? :P I would prefer something more discrete, personally. Beyond that, I love Chai tea, so you get bonus points for playing to my tastes.
