If I'm doing this wrong let me know, I'm so not used to NG

What I meant to say:

"this is Chiyo-chan"

"this is a dodgeball"

I started doing these little comics to help with learning Japanese. In almost an exact year I intend on traveling to Japan to complete a semester of courses, I aim to be fluent enough to not be restricted to hiding behind my English's speaking instructors and campus staff. however as you can see it isn't going very well.

Additionally, the character depicted is from azumanga daioh which I just finished. I have a lot of internal hook ups when it comes to creating a character for what reason I don't know but Using other characters hopefully in a okay way helps me to be creative. I'd also like to say that I think I stole the basic premise from the comic but I can't remember. She gets beat up a lot so that doesn't help.
