He's br, leave him be.
@About mapping, use more details like stones, debris etc. also make it more realistic cuz it seems like it's underground ruin and that's why you should use earth (you can mix brown earth and rock earth, try things and see) You can make basic things with autoborder tools but after you've got base for your map area you should use RAW and add details with it.
Happy mapping, everyone have to start somewhere. :thumbup:
