Friends, how do you handle a background? I admire other artists who organise backgrounds well. Apart from a technical approach, it seems that I'm very much like an instinct person. (*Often technical tips haven't helped me. Always it turned down my liveliness and lost something from an original work. Not easy.) For me, sometimes, a clear image of colour, etc come up with a subject from the beginning. But sometimes it does not. This case is not. If I dared to add something in a background from the beginning, it always turned out dull or mismatched to a subject. A worst case was "mess up." So, I do not push myself too much and take a short break now. I'm waiting for inspiration will come up. If it does not come up, I'll leave it blank or try it again from the beginning.
Btw, I've submitted a finalised image to Oxford University Press. A linguistics professor is happy. I hope it will go well!
