My first takeaway from this was not great. I originally thought maybe your style was just not a good fit for their appearances, but I looked up the official art and you are dead-on with these depictions. They are perfectly recreated meaning they were already this hideous and you did your best to help, but I guess I simply find them too visually off-putting.
Also, I did read all of what you typed because I just love having the background information behind one's decision to draw something and I mostly agree about the big lips. I've seen a few characters with them whom I don't hate, like Takeo Gōda, Suguru Kinniku, Suketoudara, and Usopp, but I'm not adding this guy to that short list. The design choice is appropriate for the personality, at least. I rather not comment further on heterochromia though.
Your family used to have game nights? I'm definitely a little jealous of that even if it didn't happen with Mario Party 8. I barely got my brother to join me a few times for some co-op, but he and I had very different tastes in gaming and dad only bothered with about half a dozen single-player titles over the years. Outside of a single friend, I really couldn't get people to join me for much of anything. There are a few exceptions, but I've always indulged in whimsical fantasy or most anything colorful and light-hearted while everyone else I grew up with was obsessed with realistic graphics and mature content.
I, too, have a habit of rambling, and I won't blame you for not reading all of this. Hopefully, you will have a spectacularly wonderful new year, whether you see this message or not wishing it upon you. Thank you, Shelly.
