@jorgevandeperre thank you very much for your advice 😊.

Actually the composition is a big problem for me, and also to decide when it's time to stop!

I do art works always in a rush, in an hour or two, and when I begin I want to see it finished, while sometimes it would be better let "rest" things and come back the day after. Not to mention that I should plan better before starting...

I know in theory, but I have to apply myself...
