I sketched this up quickly and I know that the figures still need some more work (especially deleting the ugly black lines and setting them a bit better into the landscape)
..but what can I do to make the nature even look better? Any ideas?
I really like the mood you've got going. It's slightly drowsy or sleepy and the sky looks really dusty, which is a great environmental choice. It's like a twilight although the sun is high in the sky. I do also think that the colour choices are nice, especially the slightly red grass on the lower right, but I don't get the very green grass in the centre. Is it to focus on the figures maybe? It just differs too much for me.
I also think the left figure needs a bit of work.
Keep the updates coming.^^
the green grass around the figures was a choice to keep a focus on the characters.. but it doesn't really make much sense so I will take it out
I just took a break to post this.
But sometimes I also draw stuff
i really like that waterfall idea.
i think you should use more green for the grass too. i think the characters will still be the focal point because they do stand out against the rest of the colors, and they are in the center as well.
