Lots of progress. Looks like it's almost done.

B2: "at then end" should be "at the end".
B6 is actually a four-way intersection with one passage caved in.
B7: "both the floor" should be "Both the floor".
B8 is missing a period after "ruby".
B9: "when all of the lizardfolk are" is left incomplete. I expect the word that should follow is "dead". Also, "through and underwater" should be "through an underwater".
b10-b12 should be B10-B12 for consistency.
b10: missing italicization, "miners children" should be "miners' children", & "in creases" should be one word.
b12 covers B12-B14 on the map; make map and key consistent. "This is were" should be "This is where". As for the text being cut off, I think you're just going to have to either change the font or reduce the size. You could also gain a little room by moving the key up to start closer under the title.

The map itself is adequate and I'd be very much satisfied with it as it is; however, a bit more in the way of "artistic touches" to polish it up would improve its chances in the contest as far as the Guild voting goes. Some color in Map A would be a simple thing to boost the "eye candy" factor without adding much workload.
