Guys, all of the "game ready models" you talk about in the qrt are high poly ones that have been retopologized after. They need this amount of vertices to hold the necessary details. Stop attacking this amazing artist, specially if you don't know what you're talking about.
Final result of the lamp. The great thing about modeling is that you always keep on learning with each project you make, and I plan to study a lot to keep improving so my next work is better :)
