Review time, so off we go.
First, I would have to say, it really does convey a lot of emotion even within just this short comic. You've definitely given me a lot of questions that I would love to have answers.... that's for sure. Things like, why did the antagonist want to betray their friends for power? What's their motive? (I am always a fan of complicated backstories, villain or not). Another thing, I would really like to know the progress of the events that happened within the time skip, things like how did the protagonist react after the antagonist betray them, what would happen to his other friends? So many questions.... and honestly, the fact how the protagonist went from wanting to help the antagonist to be back on the 'right' track, to leaving him to make the decision, definitely shows the maturity of the protagonist, and how it ends in a way really hits hard.
Second, love your art style, it seems lovely and the action, emotion definitely conveyed through this, that's for sure. If you have any future works, definitely looking forward to it
