Woah, I did it.
Okay, I learned a lot from this.
1. I need to make pages one-by-one and not "sketch now, finish later" as I did with this one. Then, hopefully, I won't lose interest in the story.
2. I really need some other way of making final touches. I found an artist, whos pages I could study, so before I start next 10+ page comic I plan to do couple of small training ones.
