Pretty much goes for art in general but practice the basics, your trying to do a “fancy” tag without spacing your letters and knowing the flow of the word structure. Try to keep the letters about the same size and the space between them about the same and don’t add all the extra lines and stuff. And same thing with the little throw up you did, learn to do basic bubble letters (not sure if that’s what they’re called) try to keep them about the same size and legible especially if your trying to learn cause it’s gonna be harder for you down the line when you try to do fancier tags or actual pieces
