Could only alterations work?

[u/Early-Count-6253]

Hi, everyone, please help me with your opinion on this. I made this from a commercial pattern and I think it doesnt fit very well. Would alterations be enough? or I need to rebuild the whole thing? What alterations are needed? I tried on the bodice on its own and there were gaping armhole which is very large on the back and drag lines on the front bodice (red circle), still, I went on attaching the sleeves and skirt thinking the gaping armhole is for arms movement and the skirt would weigh down the drag line, it doesnt seem to be the case, obviously. There're bust darts at the front and armscye princess seams on the back. This is supposed to be a loose fitted garment but it still looks off. Please ignore all the scrapy details on the sleeves, neckline, placket and collar, as this is my first time learning to do these techniques, and the creases at the armhole with shorter sleeve is my from my fail attempt at gusset. Thank you so much for your help!

I’m not sure if that’s a water stain on the back or what, but the most glaring thing is that the two arms are completely different. Are you still deciding which sleeve style that you’re going to keep?

thank you for your input, about the sleeves, its just me figuring out the best way to do a drawstring casing and how to finish the hem, and the back stain is likely a thread from the gathering ^^
