We were recommended to create a Master Study of an artists work, in order to help not only with our colour theory but also with testing out techniques too. For my Master Study I chose to work with a piece of artwork by concept artist Kekai Kotaki. From looking at his gallery I tried to find a more basic piece of concept art to avoid over complicating things as a Master Study is just an experiment with brushing and colour. Here is the original image:

I started out just creating the basic foundation of colours that I could paint over and over to avoid the image looking flat, I then started to work on the foreground. As time was passing by I realised I was spending too much time on the foreground, considering this is supposed to be just an experiment not a complete mirror copy, so I tried to finish up on the foreground before I roughed out the middle ground more. From here I was just trying to get the right colours down or as close to the colours as I could get without using the eyedropper tool before finishing the base colours and defining some shapes within the image.

My final outcome ended up being quite rough, with the midground and background but I believe you can get the idea of what it is supposed to be duplicating, I think the main foundation of shapes are there though my ending colour result is off, its a little light. The smoke and the mid mountains were the trickiest things to do as looking at the original artists it looks like used a uniquely textured brush meant for the clouds and the detail on the mid mountain or just applied a specific technique. I created a textured brush of my own but it did not look the same.
Before finishing I merged the layers together, duplicating the one layer and added a surface blur and box blur, setting it to soft light on a really low opacity to try and soften the whole image. I also had a dabble in selective colour to try and get as close to the original as possible. Overall I am fairly pleased with the result. The above is my outcome.
