I don't know which category to submit this to because I don't think it qualifies as a tutorial due to the lack of explanations. lol (I have to say, though, that I really don't have many tricks in sleeves... I just paint the same place over and over again until it looks right "orz)
This was my first attempt at doing a coloured painting starting from black and white. I think it makes getting the right values easier, but the overall process was very time-consuming (as I pretty much had to do the painting twice). Maybe I just haven't figured out the shortcuts. =\
Most of my time were spent between 3 and 4, and between 6 and 7.
Btw, if there's a step that you'd like to see more explanations on, let me know in the comments and maybe I can make a tutorial that's...actually a tutorial.
