If you can borrow a right handed bow for a few shots it will allow you to see what it is really like to draw and aim and shoot right handed. Drawing right handed may feel good but how it feels to be shooting that way is best found out before any expensive mistakes are made.
If you decide to go that way, you may need to do something about the left eye's dominance. You don't want it taking over some times as the arrows will be in the grass!!
If you wear glasses all the time when shooting, putting something behind the left lens can help.( tracing paper, greaseproof paper) Some wear a patch.
