My example is of course very crude. If you want a more natural movement, you should definitely do more than just rotate the bow sprite.
Maybe create separate sprites for arms/torso and allow them to move to a certain angle. Or add different animations for your character. Or combine both methods.
Yea, I am still a noob to this lol if you can point me to videos where I can learn to do those things it will be appreciated.
btw I ran the layout on my laptop and it ran better, just my computer i guess lol
