Reply To: Question regarding low poly modeling and round shapes

Hi Roxana,

My guess would be, that the flat side of the head (those 15 Faces)  is not completely flat.At least, I get no Shading issues with a slightly simplified version:

I recommend enabling the Loop Tools Addon (might need to install it from Get Extensions) and use the Flatten Option  (with those Faces Selected).
