DB Doujinshi cover

lately im talking with some japanese friends who have some stands in Dragon ball circle of tokyo comiket, we are talking about making a doujinshi but always that i try finally i dont have the time for do it , but well this time i will try to do again some db doujin and we can see how end this...

probably i will upload some pages soon to the gallery.

About the story :
the story takes places a few years after the end of the manga, the prologue begins 1 year later and the chapter 1- 11 years later ,at least 12-13 years after the original story (not gt , in this doujin universe , dragon ball gt dont exists -NO SSJ4,NO PINK MONKEYS-) you can see in the comic a teen pan or and adult goten & trunks,older gohan,vegeta,much older mutenroshi xD etc ...
the base of the story are big battles against new strong & violent enemies,martial arts tournament,dramatic moments, transformations,fusions and ecchi & funny moments like toriyama style.
i try to do the doujinshi very violent & mature like the arc of freeza that for me is the best arc of db .

This is the cover of the prologue , probably i will draw another for the volume 1 and a B/W manga covers for each chapter , but well you can see the first teaser of the doujinshi, malignant Ubb n_n (12/13 years old ubb)... goku did something wrong training this little child
