Heres a lowpoly model I made following courses at [https://blender101.com](http://). Definitely recommend that site if you want to develop your skills as a 3d artist.
Went through the process of making a highpoly model, retopologizing it into a lowpoly, baking AO and NORM maps, texturing it in Substance Painter 2, and exporting into Unity 5. A great learning experience!
