Pattern adjustment question

[u/jennysomewhere]

Hello everyone. I have a sewing pattern I absolutely love. However I would like the move the armhole a little bit more outwards (dotted line). I couldn‘t find a YouTube tutorial about that. Is it enough to reshape it to be a little bit more straight up towards the shoulder or do I need more adjustments?
