Fluent Sans

The captitals S and O, lower case m, and number 0 are not up to the standards of the other glyphs. The zero is thicker than the other numbers, the flat side edges on the capital O look awkward, and the capital S looks like there are a few nodes too many. If you remove the nodes that aren't needed on the S, the correct curvature should 'pop right out'. Other than that, this is pretty good. The thickness of strokes seems to be consistent, zero glyph notwithstanding.
