William,
Speaking for myself, not Jan, I prefer pens that don't have quite as much contour to them. The "gradual slope" you incorporated is too wide for my taste. It is undoubtedly NOT to wide for others tastes. That is not to say it is not an excellent pen because if came out looking the way you wanted it to turn out then that is all that matters. For example and comparison purposes only, I've attached some photos of cigar pens I have done that are more to MY liking. The contour is more subtle IMHO.
