This reminds me of of a couple of my fonts.
Julia, going by the display in the banner, it looks like two nodes in the S, upper center left, need to be moved vertically, one up, one down.
I think less space between glyphs would be an improvement, unless the letters are spread wide intentionally. With this sort of flat edged design, you might get good results if you put one side bearing flush with the edge of the glyph, and left the other side as is, for all letters except caps and lower case i, which you could leave as is. Nice work!
