This concerns the Maestro pieces:
The current version of the pawns (as of this comment date) is inferior to the previous one. You removed the platform on the bottom, which was a feature not a flaw; also, the Black pawn is slightly taller & narrower than the White one, now. Cf.:
github.com/ornicar/lila/blob/master/public/piece/maestro/wP.svg vs.
github.com/ornicar/lila/blob/master/public/piece/maestro/bP.svg They don't even match!
I hope you fix these pawns, soon. Simply reverting to the previous version would be an ideal fix, IMHO, as there was nothing wrong with it (save maybe that the bottom platform could have used a hint of shadow; likewise perhaps add a sliver of shadow on the inside of the knight's neck, behind his jaw). As it is, you've taken something very good and ruined it. From Staunton pawns to Hershey's Kisses -- it's as if a little kid doodled on your masterpiece. ;( Detail was _removed,_ which is always ominous; and as if that weren't bad enough, the symmetry between White & Black was broken. . . .
Thankfully, I have an offline copy. So if -- for some unfathomable reason -- you refuse to restore the pawns to their previous, objectively superior version, I will just have to create a UserStyle for the old one. :P Don't think I won't.
Finally, a word of advice: stop trying to re-draw this particular set. You already got it right several versions back. (I've been using them daily, and have noticed each change you've made. The last couple tweaks were unnecessary, but acceptable; this latest one, however, is actually a downgrade.) If you are going to make such radical changes, why not just make a whole new set? Have two different Maestros, one with Staunton pawns and one with Hershey's Kisses. Whatever, just don't mess with my beloved pieces anymore. Slight adjustments are one thing, but complete redrawings are quite another. And I think you are past the point where you can get away with doing that, and not bother more people than you please.
PS: I love these particular pieces; the way they were before was just about the best 2D chess set I had ever seen. So please don't take my criticism as a putdown, but rather a lover's quarrel. <3 You do very fine work, and it is (usually) appreciated.
