Bravo man, you have showed more dedication to getting a model in-game than I ever have. but heads up, people will give you stuff no matter how hard you work on something.
True statement right here. People get stuff on for low quality addons.
If you are stressing just to release/make something without any kind of award out of it, avoid the project, seriously.
Making something like that should not take you 4 months (in my opinion, seems like a ton of breaks) - make a project, create a few deadlines for when a part should be done in a reasonable time. To my perspective I would say the total time you did this was like an hour or so, of course I will judge it because of the quality - to me it looks like you did not put enough effort into the model
Another note: you posted this in addons, most of the time people who post low quality addons in this section will not do so well
Need help? Contact some people, we are here to also help.
You can also just stop posting addons and keep practicing models. The more experience the better you get, no need to show off poor quality addons - that will only cause more problems for you. If anything, please post in mod discussion instead.
I am not here to go after you, I am here to help you understand. Spongebob did the same exact thing years ago, he made poor quality addons and rejected criticism but kept making addons, thinking he was the most important person. Understand the situation now or it could get worse.
