I saw someone do this a while ago and honestly it was fun and also helpful as heck!!!
Basically, someone drops a link to their work and whoever reads it says one "positive" thing about the work and one "negative"
Positive - The dialogue was witty and felt natural
Negative - The actions scenes felt too short and had a lot more room to grow
Short, simple, and honestly a great way to get some quick critique! Only "rule" is that you should respond to at least one comic before you post your own link just so everyone gets something!
Here's my comic, but I'll also link my "novel" which is actually more like a TV script LOL I'd prefer getting a response for the comic, but if you want something short I suggest the novel!! Happy reading y'all :))
