I have three comments:

1. You accidentally saved it as a BMP instead of a PNG, and only gave it
the PNG extension. As a result, the file was 300 kilobytes instead of 3
kilobytes.

2. This is a rather large attachment for a public list. Suppose 500 people
are subscribed; you just generated around 230 megabytes of traffic for the
mail server!

3. There does seem to be a problem in the curve, though not the
aforementioned one. There seems to be a notch between the control point
(70,213) and the next one (81,206). Instead of a straight diagonal line,
two orthogonal lines are joined. Surely this is an error?

The relevant pixels:
