Hello,
Rather than just share the images I made some more detailed log how I went about the painting continuing from 2. Hope this helps someone
3-5
Refining the bw image. Lineart on multiply on top 100%
6.
leave background on own layer
top layer "line art" multiple drop to 40% (what do you feel comfortable)
Merge layers below lineart (not background)
add new layer on top of bg on multiply and drop some red on it
add one layer on top of bw orc painting below lineart. Overlay green 40%
add second layer on top of overlay green and experiment with another green colour (put this layer on color mode)
- selected more gray hued green and put it on 40%
7.
Start adding more color to the skin by adding new layer right below lineart (line art should be always on top at this stage and set to multiply)
7.1
added more color in the same layer (more bluish)
7.2
Made new overlay layer on top and started experimenting with green color into the eyes and perhaps adding more
green mist or some magic coming from below
8
changed background to more of violet color for now as it felt better with the greens.
now comes the fun part of painting over the lines and making the picture look sharper
- make new normal layer on top of line art and start painting. Most of the different colors and hues should be in the painting at this point
- using color picker tool right next to the area you want to paint over to select color and than "just paint"
