Every starting artists had this, to some degrees. It's something you can get over, with a lot of practice. I used to draw all my characters facing the same way. Making them turn the other way just seemed weird and awkward to me... and thb... the artwork didn't turn out so well. Many hours of practice made me come over this problem. I still have my preferences, but there's no such thing as a big difference in quality
Yeah, it's pretty much habit. I think it may correlate a bit with handedness (ie right or left handed) but I've seen many people in this forum who say that's not how it works for them. I'm right handed and draw everything facing to the left too. People, tables, Godzillasauruses, everything. But I can draw stuff facing the other way pretty decently now after practicing.
I had wondered about the right hand left hand thing being the initial reason I started preferring one direction, but if you were able to overcome it through practice I should be able to as well. Thanks for answering!
I always tend to do lighting from the left for my shading. I have had to get out of the habit, as I will turn a piece upside down, and work on the opposit side, but screw up my lighting. If you spend a week drawing people from any angle other than left, it will get easier.
