Hey 
> * What I refer to as art leaning: When drawing there is a problem artists may have is that your drawings came out a little leaned to one side, depending on what it seems your posture at drawing,
This makes it that you see a drawing you created and may think it looks good, but when you flip it or look at it through the paper in front of the light you can see how deform it came up.
> * How do I fix it now: For now, I fix it digitally because in digital is pretty easy to flip the canvas over and over again until it doesn't look leaned.
> * What I still need and ask of you: I always draw in pencil and then pass it to Photoshop to correct it. But I would love to be able to sketch traditionally and not having to fix it in digital for the drawing to not look wrong.
I try to sit up straight or from an upper or lower level with my chair, but it still looks wrong. Do you know some tips about posture or mistakes I could be doing?
