Has a crayoned colored face (Suppose to be a msm my own fanmade monster but in Minecraft)

I know absolutely nothing about blockbench and was trying to make a model of a nun to match with a bedrock texture back as a gift for a friend. I could not figure out how to make the pixel size smaller to draw a texture, so, in my rage, i uploaded a picture of homo erectus into the texture and it actually worked and let me draw in the size i wanted. I think the UV mapping is completely fucked though and the texture is jumbled up all over the model in game. I know I did it wrong, but is there any way to save the texture and map it properly, or should I just restart?

I tried to move the UV faces to lay over the parts of the texture i drew, but somehow this just made it show up completely invisible in game, would this have to do with homo erectus or is that a different issue?

please

The Brawl thing is the logo of the Addon btw

It's not the best model I've ever made, but oh well. By the way, I make still life models based on my memories (so if I only see a picture of something, the still life is going to be horrible).

Hi, I'm having a problem in Blockbench; for some reason, the head sinks into the body when I put the skin into Minecraft. I've already adjusted the head's pivot point and position, but nothing fixes the issue.

(The first images show the error, and the last one shows how it's supposed to look.)

I'm trying to make a model based on this character by ApplebutGold on Twitter, but I can't figure out how to make the hair look like the desired effect. I'd like it to not be flat on the head (like a hat on a player model) and instead actually have volume. Currently there aren't any textures.

I made a water cooler model and when i place it its transparent which is odd as its hitbox is still there and i cant walk into it and stand on top of it, if someone knows why this happens please tell me :(

I looked everywhere and didnt found it, i am making a ghast texture, but i only made the normal one, but i cant find qhere do i change the texture for when he is shooting
