Basic techniques for drawing letter is "CRAP" short for Contour, Repetition, Alignment, Proportion.
Free open source program was used to create the type/letter.
The feedback for the letter O was that it was too wide & might not be legible. So I decreased the weight of the letter while keeping the irregular shape on the X height.
The original sketch was inspired from a font called, Gabriola.
The serifs for the letter was too wide/open so I widened the frame distance.
