I'm struggling with this choice.
Naturally, I don’t have enough time to make all four versions for the final drawing, so I’ll have to choose two options. Therefore I really don’t like trying to change the lighting/shades - then it’s very difficult to stop and even more difficult to choose.
I think I'm more likely to go with the first option with the red sun than the second; and from the last two I will choose the blue option, but I will try to add something from the third to it. What do you think?
