Good progress overall! A few comments if I may:
- Watch the drop shadows. I am not sure which program you used, but sometimes your shadows make the walls look like they are floating over the ground. This can be fixed by adjusting the placement of the drop shadow. In photoshop it is the distance and the spread markers that will fix this for you.
- In the first map, the spot marked 1 looks as if your dias goes beyond the walls. If that is the look you are after, disregard this comment. Otherwise, if you place the dias layer(s) below the wall layer, it will take care of this problem.
- The altar needs some loving as well. With the shadows you have, it sort of looks like it is floating.
- THe spot marked 2 on the second map presents a little problem. Again, it is interpretation of the map, but logic states that if this is a dungeon, the pillars in the middle of the dungeon would be as tall as the wall, so the drop shadow would/should match the wall's. Otherwise, it appears that there is no ceiling in this dungeon. Also, the spread of the drop shadow needs to be fixed (see the first list item above.
- The spot marked 3 on the second map is another interpretation. Again, this probably goes towards layering, but if the pillar does actually glow, the corners of the walls in this area would have no shadows. See, that is the problem sometimes with using layer effects, they just do not work. Try this: Make a new layer above the walls, then press ctrl+alt+g. This will clip the layer to the walls. Fill this with 50% gray, then set the opacity mode to soft light. Then use the dodge and burn brushes to make your shadows. A soft brush will do the trick
All in all, a good tut. A few minor points, and you are on your way to mapping masterdom!
