Don't be shy! I get it, first entering a group it may be hard to speak up.. but what's easier than just introducing someone's self?
You can start with...
Well anything! No real way to do it.
For example, hello guys!! Never said my name even tho my nickname is big written up on here but it's Oliver! Nice to meet everybody.
I'm a silly sparkledog undercover, I love flashing colors and lights but sadly my eyes are too weak for them,, So I have to limit myself.. even when drawing I get headaches ahah
I really really love lapfox! (The artist), Renard, even tho he's very popular, he's still amazing. So many choices, so many albums it's insane !
... Well I shall not talk only about myself.. why don't you try?
