i really like this design of gabrielius, and i consider it to be one of your best characters, imho.
to recap on my thoughts on this character,
thats one of your coolest designs of your madness themed character, its a very good work, and i really like the white+blue outfit, the golden chain and the nice glasses on him, while the band aid is a clever little detail!
in this pic he holds a can of coca cola and he's giving a thumbs up, which adds more character to his expressions, while the blue+black background inserts a new level of style for this good characters aesthetics.
all in all, splendid work, keep it up!
