Merge back sleeve to back bodice by matching notches. Do not overlap sleeve head to armcye, notice that they are close to each other in uppermost section and create a gap in bottom section, and they overlap only at armpit/side seam (which is ok because the cape does not involve armpit at all).
Repeat the process for front bodice and sleeve, matching sleeve slope to back (as much as possible).
Sleeve head will be higher than shoulder point by about 1cm (for the cap ease that normally is needed in sleeves). Redraw shoulder line on both back and front from high shoulder point to uppermost sleeve point.
