also, the fact i'm using 1x2FF 0.25 vertical small bricks and 1x1FF 0.25 ones + corners, the brickcount went ridiculously high when i built the new school;
if i ever try to apply to inDEV, i'm pretty sure i will be rejected, because the walls are basically spam, but at least there is an outside color and inside too now.
EDIT : Feedback is appreciated.
