这是一个真实有趣的案例，甲方希望用插画的形式描绘出自己与女友未来想一起完成的心愿（给出了20多张参考视频截图共计6个约会场景以及文字描述），由于时间短任务重，想要在2周时间内凭一己之力手绘创作20张场景插画几乎是不可能完成的任务，设计费及沟通改稿成本也较高，但借助 midjourney 我们可以快速绘制出这些画面，今天便把创作过程和方法分享给大家，以启来者。

性价比高。站在客户角度，对方只在意画面最终的视觉效果是否准确表达了自己脑海中的画面，能体现出人物角色关系和特点、场景氛围感和故事感，而不在意是否是用人工手绘的方式完成画作，AI绘画极大地提高了出图效率以及降低了设计费用，对客户来说是性价比更高的选择
无痛改稿。作为画师，以往在创作中最痛的点应该就是无休止的改稿了。AI绘画极大减轻了画师改稿的痛苦感受，如果一张画作经过2-3轮人工P图修改后仍不满意，直接用AI再多刷几张图也许会更好
人物一致性。系列插画中同组人物特征较难保证前后一模一样
人工改稿。AI绘画出的图在实际商用过程中无法一次性全部满足甲方需求，需要后期人工干预修改
协同合作。多人协同创作完成，需尽量统一画风、人物特征；为更好在线协同工作，在送审时运用了「石墨文档」，把所有画稿放在石墨文档中，并且写好项目背景、审核规则，让甲方按要求提交审核意见，画师也可在线同步查看进度
推荐一个扩图软件「Upscayl」，可以把Midjourney生成的图片画质提升到印刷质量和尺寸，方便更多商用空间
