Revolute

Based on text in the banner display, you probably have too much space between the right edge of the glyph and right side bearing, for lower case f. The same is possibly true for capital Q.

If the letter pair of lower case f & l doesn't look cramped, that would be enough space. As is, the f looks miles away from the g, and Q a bit too far away from R. The high tail on the f won't make near contact with many letter combinations in text, other than l.
