The line thickness variations are fairly obvious and would bug me... Look at "Q" vs "Z" for example, or "N" vs "M", numpad "7", etc.
Looks like they could possibly be caused by remelting or poor legend seating during the second shot, but it's quite inconsistent.
Also that 3... the "#" is too far to the right, the line thickness on the curly braces is too wide and the tilde is... rather an odd shape. The letter spacing and sizing on "Pause" and "Delete" vs "PrtSc", "PgUp", "PgDn" is also off.
They look nice, but they're not quite GMK quality.... yet
