My friend tells me to call him Oni-chan and he says he likes it, I actually like the name, it suits him but does it mean anything I wouldn't know of?

no

Explanation:

well i just looked it up and it says older brother ig lol

well seeing i am an artist and i actually did a self portrait; i will describe how i painted it.   i used acrylic on a stretch canvas about 4 feet wide by 6 feet tall. i painted myself smiling in a soft pink long dress, white tile floor sitting on a white couch with a table behind and a vase of gorgeous flowers.   i also had a round white hat with a soft pink ribbon through it laying on the floor and on the table behind me was a lit candle. i kept it simple but soft and romantic.

can you rephrase the question? was there a picture to go along with it?
