Is this on axis properly?
Nup, its off axis. You can rotate the whole thing to get it back on axis.

When you start the drawing, make sure your lines turn either blue, red or green before you lay them down. Also when you draw lines off those they should also show the appropriate colour and when you join lines that are square to other lines, a little coloured square should also show up.
Also look for a blue square or line which means the midpoint.

Someone else might be able to explain it better.
