@jtandy I try to get to it over the weekend if I can't make it during the week but the past couple of weekends were quite busy. I will always come back though :-)
You have developed good control of the strokes. Now it is time to pay attention to spacing. Spacing in Copperplate is almost automatic if the exit hairlines are drawn consistently. On the other hand, it is easy to see variation in spacing too.
In 'nymph' look at the 'm' and 'p' - the spacing between the three strokes of the 'm' and the two strokes of the 'p' should be identical. Can you see that the strokes in the 'm' are closer than the last stroke of the 'm' and the first stroke of the 'p'? The two strokes of the 'p' are then closer again. Each of these strokes is one hairline (i.e. base line to 1/2 x-height, or waist line to 1/2 x-height) apart. These should be evenly spaced.
The spacing in 'mint' and 'vim' is better even though there are i-n and i-m joins to mess things up.
The closing stroke of the 'b' should not go further away from the main stroke when the hairline reaches 1/2 x-height. At this point, bring the hairline in line with the slant of the letters - or even turn back ever so slightly. This will even out the spacing in 'bin'. BTW - the same applies to the last stroke of 'w'.
The longer strokes are not even all the way through. Also, the bottoms are not squared properly. The squaring should be neatly done. The 'm' in 'mint' needs a lot more attention in this regard.
Lets give these words another try.
