I don't see why people would want to make Western comics readable from right to left.
I mean, we're not in Japan so why would you do it?
The whole concept of having to read from right to left kind of hurts my eyes anyway x.x
I can see why some artists would do it though, since most of us across the globe have at least some influence of Japanese art with us wherever we go.
But I don't really think completely adjusting to their way of style is ideal <.<
That's what I think anyway
Have some fun with your art overall though, even if you want to experiment the manga style out anyway
