Wonderful work, and really well thought out. There's always tons of plot holes when it comes to time travel itself. Sometimes we don't do the research, and sometimes the research is faulty! You've really captured the moment in these pages though, and it really did feel like the character was talking to the reader. Compelling stuff my friend, I look forward to seeing where this goes.
I just had to say, I found this seriously impressive. You did some great work on this man, I think the interactivity really added a lot to it too, let it be a lot more than a normal physical comic could be.
Man, I hope you get an ace grade from this because it really shows a lot of effort and thought!
