Yes, and i see not artefacts in the surface.
Topo is not that important than most Artists think. Yes its importatnt for deforming character or hard surface that otherwise wont get a good shading.
But its irrelevant if its a background object or it gets rendered very small. Have in mind where is the asset used who is going to review it. Why would it be important to have "godlike topo". In a lot of cases it isnt. Yes you need to learn good topo and use it if needed.
