It is important that you do not just merely copy the artist, instead that you try and figure out the main features in their work that relate most to your own project. In the early stages of analysis of a new source artist it is perfectly valid to keep your sketches and annotations loose, this will give you a greater margin for freedom of expression and if you are not to precious you will be inclined to explore through greater experimentation. At this stage an iterative process is essential - create multiple quick sketches each time making small changes/enhancements. This will demonstrate that you understand your own body of work and that you have not just stumbled upon a final output purely based on aesthetics, moreover, this will bag you essential process marks. Eduardo Chillida is known to derive his visions from two anatomical forms, the torso and the bust. In nature there is perfect harmony and proportions hence artists like to explore it to create more coherent designs. When looking at a new artist it is also good to compare and contrast their ideas with those of other creatives (for this example a great comparison would be the built and conceptual work of architect Santiago Calatrava who focuses on the movement and the articulation of the human body to inform his structural designs).Lets consider two conceptual ideas observed in the work of Chillida:Construction vs deconstruction. You can start with an empty grid (an entire void) and gradually fill up the space or on the contrary you can commence with a pre-determined mass and then create the void by eliminating sections of it. This will create varying forms of relative densities, exploring the perceptions of weight and depth. Fragmentation. For this it is important to consider how your sculpture is going to sit within its surrounding context. You are in control of the form of the sculpture but more importantly you can also dictate a given viewing experience. Through layering and depth you can begin to obscure views and create false perceptions. From one side the viewer will see one thing and memorise that view and then try and incorporate the previous image when viewing the sculpture from a different angle. However, if you have layers that can only be observed from one side then you begin to create confusion and intrigue. You can dictate and enhance emotions.
