I thoroughly enjoyed what I just read. The simplicity of the style makes for very easy reading - it's not cluttered at all, and the dialogue we are given hints at the type of setting and society that the characters are placed in. That means you are doing very efficient world building WITHOUT having to spend hours drawing backgrounds and settings, so far!!
I like the loose way in which you have used colours and lines. For example, how the orange colour of the flames is not contained by the lines in the first comic - that looks great!
I really enjoyed the comedic pacing too. Everything so far is delivered in a pleasing way that had me smiling and chuckling as I scrolled.
I don't have any negative feedback, honestly. Going forward I would say continue to focus on the quality of your dialogue, and continue to value the importance of small moments between characters! This is a great start, and if you build upon this correctly I could see it being a big success
Keep it up!
