Before editing the layout of the composition one more cave piece was tested, unfortunately I could not record this piece however I have a series of progression pictures of each individual layer.
The first layer composed of a rough sketch line art where a basic idea was created. Further more rough ideas of highlights and the direction the light entered the cave at.
Then next step was blocking out the colours using pen pressure and a chalk brush this way the colours blended together more easily. For this step a class mate helped me in the methods and how to develop a more professional finish.
This is how the cave appeared after the image was blocked out along with the specular light and radial light being evident. In parts the light reflected i added in a slightly more saturated value creating a lower light space. The next step involved adding increasing more detail.
This is where a higher opacity brush was used however this was later lowered to blend in with the under layer. The final step was to include in more foliage and detail within the image to finalise the composition.
This is the final composition I believe the level of detail is successful as well as the various tonal values. I also believe that a little more story and 3d aspect is identifiable within the final image.
