Well, I enjoyed your comic, it's a cool story.
I'd have like to see it in colour and perhaps with some clearer drawings, so that you could tell it's Mordor, even if Sam And Max hadn't told you. The LOTR scenes have a distinctive look I'm sure culd be done nicely in comic. Actually I think it would have helped if you'd used a few larger boxes for some frames, sometimes things got a bit crowded. Essentially, I could read it and got the sense of what was going on, so that's good.
The writing was really cool and fit in nicely with the Sam & Max style. If LOTR was owned by LucasArts, I'm sure Steve would have done something like this in the Insider at some point. Nice work!
