This is a picture of a street scene in an Allied Sultanates town.
An amazones or humans view of a fennekim's city-quarter.

That one was first drafted using the "full arm" method, and then refined and corrected using a ruler and "point of view / of flight" to aling the angles mostly correctly.

The "Full Arm" ( I think the professional term was "kinaestethic method" - it's using motions of the whole arm to do the draft as those are controlled by the creative part of the brain, whilst the figner and wrist motions are controlled by the logical part of the brain ) method however sucks at straight lines - again, unless trained.

But mixing both techniques ( the trees are still arm-based ) seems to be working good.
