first 2 sprite Sigg's - DAVID
my first 2 sprite taggs ever

cnc/

first one is overly over saturated , over sharpened in some areas and the smudge to the left is kinda off flow , try to make your text closer to the focal maybe drag the whole signature more to the mid.
second one is noisy and totally random try to organize the elements a lil bit but i love the circles , text in this one is meh remove it or try to move it more upwards with changing the color .. yellow maybe
