not bad man, i mean its your first track, but things could do with some work, the vocals dont work, they dont sound in key, and piano is nice, but doesnt carry the tune like it is trying to, and seems a little off it doesnt work with the strings properly, and the drums are very weak, try keeping it simple, keep things flowing melodically, its just a bit all over the place.
now this is kinda off topic but i might rant a little, why would you want to show anyone your first finished track? your 15, im assuming you have just started producing not to long ago, why would you need someone elses opinion yet? realistically your not going to be any good for years yet, its a long game, you should be able to listen to your tunes youre making and make judgements for yourself on whether they work or not, why not try listen to music you enjoy and place them side by side? imo you really dont need feedback so early, you gotta get to grips with so much shit first, before thinking about making a tune for other people to listen to and enjoy.
unless you posted it simply to ask some people if youre on the right track, then yes, you are. keep at it.
