For Vanishing Point Page
----------------------------
[] Typically, the solution is as follow: 1) Create a vanishing point on the horizon outside of the canvas to the left. 2) Draw a diagonal line from that vanishing point, connect it to the point where the first beam meets the right rail. 3) Draw a vertical line from the point where the two rails meet over the horizon. 4) Cross the diagonal line you made in step 2 with the vertical line you made in step 3. Draw a horizontal line across the point where these two lines meet. You can now use this horizontal line for the second beam. 5) Repeat this process until you finished drawing all the beams.
Instead of the manual method above, you can use Krita's vanishing point assistant tool to make the whole ordeal much easier. (to the vanishing point assistant method instructions)
