Only tip is keep practicing. Personally only advice i would give is dont connect letters. Like your i with the c. try keeping them seperated.
just takes time, dont forget your basic letter structure, comes with everything graffiti... time and basic letter structure, NEVER GIVE UP AND DONT COVER REAL ARTISTS
LOVE IT! The essence of the tag is movement and structure. It looks like you have it to me. From here out, work on refinement!
Even if you dont like the look of the letters, practice all different letters so you can have a grasp on all styles
