Costom anime character for game

So, im making this post because m feeling kind of discouraged, ive been developing this game for a while now. and people say that the model looks really bad. They keep telling me to just use the regular blocky rig, but i want to be different

I feel like its just a phycological thing but im genuinely not sure and im so confused on the feedback im getting. I told people that i could just improve the model but they said at that point just dont make it on roblox

Can i please have genuine feedback on what makes it look bad and what i can change, because i REALLY want to do this on roblox.

like is it the hair the clothes like what is it i feel like im actually going insane. Poeple tell me i would have completely different feedback depending if people knew it was roblox or not but like i cant anymore.
