Looking good Ashok :-)
Like Sandy said, the loops should be the same height. I also think they would look better if the tops were a little more pointed and the widest point was a little lower than the absolute top of the stroke. This is just an opinion though.
In the second example, it looks like the straight strokes go a bit lower than ones that turn around at the base line. It might be the angle but it looks like the bottom of the 't' and stem stroke of the 'h' are lower than the second stroke of the 'h' and the following 'a' in 'than' on the last line.
Does it look like the 'e' in 'enigma' is leaning to the right too much? If you notice, the shade is thickest at just above 1/2 x-height - this causes the round letters to tip over. Also, the slant is a bit off I think.
These are minor things in the overall scheme of things. I think you have a very good sense of the balance and shape of the letters. I think the last group of 'misfits' will not be a challenge for you at all. Lets get to the f, r, s, x, z. You have the whole minuscule alphabet to play with now so come up with any words you feel like.
Regards,
Salman
ps. The joints into the round shape are still 'going in' a bit too low - watch out for those.
