Hope we are all having a nice weekend, whereever we are we reading this.
Made this a while ago and fortunately i have it well documented in my gallery.
This was made with freestyle but i used a ruler when i feel the need.
Process
Started with the basement on one drawing sheet. Started with 6h to sketch out the shape.
And then i sketched upper part of the tower on the next drawing sheet so it can be placed perpendicularly with the previous.
With the shape done, i started adding details from the bottom - up again.
Used graphite pencil 4b, 6b, and 6h, for this.
Happy sunday to everybody
