Good post and nice paintings @inber
Its great to have an object to come back to and draw again and again in order to relax or warmup / sharpen skills. You'll never sit there wondering what to do and waste time, just draw your favourite object and at least do something.
I like drawing eyes! Yesterday I made a post about keeping up drawing training when you dont have much time by making sure you do something, even if its just a small drawing and i used eyes as an example.
