Sadly, the development of Nude Byte is currently on hold for a very long time now. (Not sure when I can resume) And it's the reason why there's nothing new to play in the game.
But I do see your point when it comes to the Gallery's Achievements. To me, I see those portraits as just portraits. I just let them be empty or rot for all I care. But to some people, they see it as "Hey, I look incomplete, do something about it!". That wasn't my intention when I made those. I simply think they're optional things. However, regardless of my intentions, that became the impression some people felt. I didn't realize some people would find it stressful.
But as mentioned before, I can't really remove the Gold/Silver/Bronze either. That will disrespect the efforts of some other people.
I'll think of something to improve this part sometime in the future. But I can't make any promises.
On another note: To me, showing hatred in messages might contradict your goal. Let's say, you wish to share ideas that can improve something or point out something. If you mix hate/insults in this, there's a higher chance that people will disregard your message and think of it as trolling instead (since they're butthurt), ignoring your advice, whether it's true or helpful. Without the hate/insults, there's more chance that people will read it. (Or possibly not. Realistically, most likely not. The world is unfair, you can't really tell when people will listen no matter what we do anyway. But, personally, I just don't like making people displeased) But really, we're all different kinds of people. If putting hate in your messages is what keeps you feeling relieved, you do you. What I said was just my analysis, anyway. Feel free to ignore it if it's not helpful for you.
(But just remember that most people don't want to see negative stuff. We all have the option to block/ban/report, after all, if things become way too problematic)
I wish I could give advice when it comes to creation. Sadly, I'm not a good teacher or someone who can give motivational speeches. All I know is that I'm aware I will never be the best at making things, but that shouldn't stop me from doing what I want.
