Finished Sketches for posters 2 and 3

I just finished some sketch out ideas for the remaining posters in the series. Second one is basically worked out. The third one is in it's early stages. I am hoping to get that worked out in the next couple of days.

Ironforge. This image is of the inside of the cave (that is the city) and of molten iron pouring down from the ceiling.

This early sketch of Stormwind is very rough and gives the overall sense of what I am looking for though it is not very detailed.
