Yura nodded. She wasn't going to make any assumptions about him today. She just wanted to see where he was at and help him improve. So let him pick whatever target he was comfortable with. He was likely to do his best that way. She watched him choose and followed him toward the dummies. Then she immediately picked out a couple of problems with his stance that she knew would send the arrow askew before he even fired. However she let him try to work it out first. After all this wasn't a skill he'd perfected and could just pick up again at a moment's notice. Fortunately the second time aground he did better. 

Yura nodded, offering him a smile for the first success. But she did have some help to offer. She stepped around him. She moved so that she had his same sight line and then nudged him so that he was perfectly centered. Then she kept adjusting his arms and legs until he had the proper stance. Then she patted him on the shoulder and dropped her hand.

"How's that? Uncomfortable? Good. It won't get better until you're used to it then it'll be as natural as breathing." 

Wasn't it great to be a ninja?! She'd grown to love it at least.

"How can I put this?" She looked at the target, then back at him. "Okay. DON'T focus on your aim. Your whole body needs to be positioned right and at the right level of tension or it's going to go awry EVEN when your aim is perfect. So your aim doesn't matter if your [i]delivery[/i] is off. Get it?" She quickly looked him over and saw that his arm was beginning to shake. "The tension on your bowstring might be too high right now. But you'll get stronger and work up to it."

"Oh, one more thing. Let go by [i]relaxing[/i] your fingers. Keep everything else firm, especially your bow arm." Because again, the stance mattered more than aim. The aim depended on the stance. His fingers could tilt the arrow up or down as he released and/or his bow arm could begin to drop before the arrow finished coming off of it. It was important to realize that. 

She took a step back, "Now go for it! Use the rest of them in a row." That would give him several chances to use and remember her tips.
