Yuyu started off in the same vein, being very similar to muramuraaki at first (and you could see when he was experimenting with other artists styles). He developed a very lovely style of his own after a lot of it.
danogoat said: how often should i use koyukkuris slurring? its really hard for me
Baby to Kid Yukkuris Slur all the Time, meanwhile Adults Slur only when they are facing absolute pain or absolute fear (or their shithead level is over 9000). Aside of those cases you may avoid the slurring.
