Its alright to ask one of the higher ups for training and for us to furtherly advance your story line to that you can get the powers you wish to achieve
but let it be known
that if you dont have an idea of what you want us to train you how to do, then we wont either. if you dont know what powers you want to use later on when you rank up/get stronger, then we wont be able to help you get there. that is why you dont start off with all your abillities when you join the village, you have something to aspire too and we can help you get there
when it comes to training chakra control can only extend so far, and if you want to use more taijutsu i understand. but when you approach me and say "i want more power" and i respond "well what do you have in mind" if you respond with "i dont know" or "what do you suggest" then i probably wont train you, you need an idea of what you want for one of the higher ups to help you out.
