I have seen slot of messages in this chat. If you need my help anytime. Just tell me about it. 
You could use Medibang and erase the white parts
It’s what I use to put character’s into splashes. Or you could send me the character’s in the poses and I can help.
Use power point it works if you have new version.
I can’t remember how to do that. It’s been a while since I started using it.
What do you use. Maybe I can give you a tip on erasing backrounds
Use the eraser and erase it. Then zoom in and make your eraser smaller and erase the small parts. I hope I was clear.
Alright if it doesn’t work I’ll send a vid of me doing it.
Kk!
What Pixlr version are you using?
Wait why is my name at the top. Not trying to sound rude. Maybe you put it there accidentally. 
Update
I now again need a personal artist for “The Young Actress” Remember it’s in Ink and Limelight. If you’re interested send me examples here, then PM me!
