Sasuke wasn't too sure if he'd done a good job, it looked to him like it was the same as always. Yura's praise surprised him a little then, and he allowed himself a faint smile at being told he'd done well. He supposed he had really, given he'd done about the same as usual even with a new technique. Sure, it would be some time until he was on target all the time, if ever, but the fact he had a chance to improve made working for it exciting. Maybe a bow wouldn't ever be considered a ninja tool either, yet that wasn't going to stop him from practicing.

"That all sounds complicated..." Sasuke mumbled in regards to the other factors. Air currents? He wasn't even sure what that was, it sounded like something that was way above him though. He'd always figured you just aimed an arrow and fired it, so hearing the fact there were more aspects to it made archery a bit more daunting. Simple target practice would be fine however, that didn't take much other than a steady hand, and the know how, both of which he now possessed. Firing at a moving target? Particularly, a target that was another person? He wasn't prepared for that just yet, and thankfully Yura was sympathetic to his concerns. 

Nodding his head at the directions to keep going, the young Uchiha hurried over and fetched all of his arrows, noting that two had become dulled. Yura was more than happy to offer to help with that, but she wanted him to continue with what he had left. His arm might be sore from the strain, but he knew that pain was all a part of training, and if you weren't sore then you weren't training hard enough. 

Notching another arrow as Yura began to leave, Sasuke was ready to resume his training until she mentioned leaving, lowering his arms and glancing back at her with a slight bit of worry. What if she didn't come back? There was no way of knowing where Itachi was right now, and while he couldn't exactly fend off his older brother, he felt a little better knowing where Yura was. Worried this might be goodbye, he tried not to jump at the offer of joining her, though a small smile of relief washed over his face. "Um... Okay! I'll come!" he answered, placing his arrow back before setting both the quiver and bow down, hurrying over to join her. Slowing as she addressed him with another question, Sasuke frowned in thought and gave a small shrug, not sure honestly of when it had been. A few days? Maybe longer? It was difficult to answer when you'd lost track of time, he wasn't even certain of how long it had been since the massacre.
