Sometimes, I stop and think "What if my so-called art is not that bad?"
Then I take look at it, and, there is no doubt about it anymore, it is that bad.
Better go to sleep so I will not throw my computer out of the window (which cannot be open. Actually.)
I wonder how many grammar mistakes could be found here.

(These illustrations are quite old, anyway, do not worry, I am working on commissions all the time.)
