It's just getting to a point that covers a confrontation that pretty much anyone that's a fan of both wanted to see, but nobody else dared try writing for fear of messing it up.
Also, if a crossover story manages to have some epic scenes, stays true to both sources, doesn't break characters, and fits both sources without breaking the lore of either, I'd like to think it's a winner.
My comic only breaks one bit of the MLP lore now, and that's Lyra being a spy, (messed up by episode 500 and 'Special Agent Sweetie Drops', and the episode 'Amending Fences' because another unicorn will be joining the cast later).
I never wrote out the last chapter on FIMfiction, deliberately so I didn't spoil the ending for those reading the comic. Let's just say I have something special planned.
And thank you for noticing the comic.
Each page can take weeks to get drawn, especially when 40k stuff is involved as it's often heavily detailed.
