I made my first UV map manually it's really ugly and I need help!

Hello, So I wanted to  make a UV map manually, it looks beautiful in the UV room but when I go to the texture room and try to fill the spaces it is just ugly.
I managed to fill one part in red but that is it.  The other paint strokes were for autotpo and I'm not sure how to erase those yet.
This applies to painter too,  I have no idea how to fix this.
Any help would be amazing!

This is not the correct steps to transfer to Paint Room

The steps are Sculpt room > Retopo room > bake > Paint room.

Paint tweak and uv works over the same mesh type.

Retopo and modeling room works over the same mesh type.

Sculpt works over surface and voxel meshes.

At this stage the best way for you is to export the model from uv room as obj or fbx, import into Retopo and the from there Bake for PPP to transfer the mesh with UVs to Paint room to texture it.

Take a look to understand the process:
