SYN - A whole lot better, those letters look real clean, and solid, keep trying to get the bars the same with, they're a little off in some places - like the K and R look a little small and the S a little big. The heights and spacing are good also. Try messing with connections a little, just don't sacrifice the letters and work on that handie, it'll help with the flow of the piece.
GEMER - I don't like the hook in the G, the first E's straight, the MER could be bigger and the thickness of the last R gets too small. Overall flow is decent but the ending E and R gets pretty plain. The right side of the M gets too small and leans too much to the bottom right.
Norf - work on straights, you don't understand letter structure
NAKE - Try using strong contrasting colors, the ones you used are too close in lightness and darkness which makes the piece illegible.
