the source used is a wire sculpture I made in one of my classes; always choose reference images that have some potential to give ideas and one should deviate from it and create something original by itself. the result should be much better and have a stronger impact than the reference used.

source parts

here is a screenshot showing different layers for different lines that you want to duplicate

warp each line in a different shape

By using the warp tool I was able to obtain different shapes and arrange them in a way that could show the shape of the reference pic underneath.

here is the head completed; you can see the reference image under it; this is helpful in getting the shape you want and also the depth; as the body is completed, lines that are far from view (such as the back and back legs) will be thinner and smaller.

here are the parts that make the horse. to keep things organized u want to put layers in groups and name them something u can remember. for example; I had one major group for each part: the head, the legs, the chest, the body, the neck and the tail. I also made a group for the eyes but deleted it later.

as you can figure by now, there are lots of layers organized in groups; however, the total size of the file increased to 80MB and it was very hard to move or edit or do anything else with the horse; therefore an easy way to "reduce" the size is to convert it to a Smart Object. Smart objects are like images of the psd file and are very easy to manage. To turn the horse groups into one smart object you go to Layer-Smart Objects-Convert to Smart Object. If you want to make changes to it, simply double click it and a new psd file will open; any changes have to be saved and will show up in your working file as well. Smart Objects save lots of time when working with big files.

also u can see shadows going beyond the outline of the horse; to get rid of those u can either mask them or erase them

To make the sphere I have selected the source image while living plenty of space between the image and my selection; this allowed the Spherize Filter to give a convincing result. I have also used the Ellipse Tool to make a sphere like circle to which I applied the Spherize tool again.

I have created a background using the Radial Gradient Tool. File dimensions 1425*1500 at 150 dpi. I like to set my files at 300 dpi for a better resolution in case I want to print them later but in this case I went for 150 because the file was too large.

I've created the planes with the Polygonal Lasso Tool, filled the selection with a grey color; Added the bottom orange and the shadows with the gradient tool. I have also dented the plane so it looks like it's about to fall; you can do this with the warp tool

I have added the horse and some more spheres and planes and arranged them in an asymmetrical way to give a sense of balance to the whole image.
