Your fonts are looking more and more beautiful.  You have to make choices as you go along.  Consistency should be one principle.  The traditional writing is with a pen-tip with a 45 degree angle.  That angle needs to show up in all characters.  So the end of द showing up a rounded end does not fit within this consistency.  With a 45 degree angle of the tip, one cannot draw a rounded end.  The same thing with signs like े ै ो ौ where the 45 degree angle should show up, and not rounded tops.  I am giving these suggestions following some of the principles I followed in designing my own Madhushree font.  Since my font is not unicode compliant, I no longer use it.  I can no longer type using that font either.  For some reason, my Mac does not allow it.  Here is a sample from my Saṃskr̥tasubodhinī:

I also prefer the top line without gaps.  With best wishes for your project.
