A very interesting portrait, done in a unique style of a series of lines. I really like this, @norihany ! Very stylish... <3 And his expression is so grumpy, too ! You emote well with your portraits :)

Are you traveling soon? I hope it will go well....

As for when we do become monotonous, I am not sure. Humans are very complex. We crave both safety and excitement... at once. Maybe, though, in general, it is easier to be safe and complacent....
