Is there a limit to how many attacks I can make?

Hello everyone! I know that this might be a silly question (and please tell me if it is haha!), but this is my first year doing ArtFight and I’m worried that I might be making too many attacks.

I’ve created 19 attacks so far, most of which have been headshots (so relatively quick for me to make). I’ve been working with traditional and digital (sketching on paper and cleaning things up on digital), which also makes this easier for me I think. I’m worried that this might be a huge amount. I’ve been working on them before and after work everyday, and I’ve been having an absolute blast, but I’m an anxious person and I just want to make sure that I’m not doing anything wrong.

Anyway I reread the rules and didn’t see anything about this, so I just wanted to ask around for other opinions.

Thanks in advance! :)
