This amazing era of work is known for it's highly detailed work and limited palette of color. Begin your research with the links below and then begin your sketch. Animals are a central focus during this period and you will need at least two photo references of a horse or the animal you choose from different angles.
For this project you will only need to produce one piece and doing so will require you to create several pieces and assemble them to represent the animal.
Your work must be freestanding so it will require consideration of how to structure your piece so that it stands. Consider using the tail or even an environment to ensure that it helps support your work.
