There are a couple errors that are more prominent such as a couple letters where I ran out of ink and one "d" that the stem didn't get connected to the oval. Any further feedback you can give on the image posted below would be great!
Your stroke width and slope are consistent, which is great!
Positioning the downstroke on 'd' is quite tricky, and it's easy to leave a gap or overlap the oval, creating a flat back to the letter.
Try this-
Make a letter of at least 6 or 7mm x height. Larger lettering makes things easier to see.
Create the oval, as normal.
Judge the position of the downstroke and place the nib edge at the top of the stroke.
As soon as you start the downstroke look at the point on the curve of the oval,
where you want the stroke to just touch and no more, as it passes.
In other words,
don't watch the downstroke but look at the target point.
After a short time, this becomes a good practice to adopt. It isn't foolproof in all situations,
but it does make for more accuracy most of the time.
My apologies, if you're already using this technique!
