Wizards Tower Part Tres

I'm full into painting up my desert terrain table.  In order to do it economically I use craft paint in lieu of the GW or Vallejo paints.  I typically paint desert using successive dry brushes of snakebite leather, bubonic brown and bleached bone.  I used this online tool to convert those colors to Delta Ceramcoat.  Not a perfect match, but close enough that most won't notice. The conversion colors are Golden Brown, Spice Tan and AC Flesh.  I should have some photos to post this weekend.

One thing I learned is that I should have sealed the tower before painting to reduce the amount of paint I used to get decent coverage.  I also wonder if I went to light with the color choice.  Painting was really simple.  Base coast of Dark Burnt Umber.  Then successive dry brushes of Mud stone, Sandstone and Raw Linen over the whole piece.  Then in the middle of areas that still has the stucco in tact I hit it with a little Ivory.  To paint the stucco areas I used a circular scrubbing motion focusing closer to the center with each lighter color.   

Here is the tower, though I still have to do the base and some small details like the dome on top.  What do you think?  What do you think about the dome on top?
