??? Did I say something wrong? I'm just giving you constructive criticism.
Since you didn't take the hint from "lol, lmao" that I don't respect how you conducted your critique, I'll just be straight forward.
You could've been a lot more polite, for starters. I think opening with "I'm a humble artist" and then spending the next two paragraphs deploying a condescending lecture about artistic cohesion comes across as inconsiderate, unnecessary and hypocritical.
If it helps you, the reason the NPCs are stock images is because Nowhere, MI is a homage to Crypt Worlds, which has the same style for its characters. Nowhere is a collage-style game. The dissonance in its style reflects the chaotic nature of the town you're exploring. That's the point. You're welcome to dislike an artistic choice, but you aren't the authority on whether or not that choice was a valid one.
If you were expecting me to listen to you and agree on your stance, you should've been courteous and at bare minimum spoken as though we were equals. Remember that I didn't ask for your opinion, you provided one unprompted. When you spend 2 paragraphs telling me how well Hylics and Yume Nikki manage their aesthetics and how poorly I constructed mine, it comes across like you're really insecure and need something to punch down on. I hope going forward you'll be more polite when talking to your fellow artists.
