I just finished a low poly model of a wood plane. The model is 2981 triangles and has a 1024x1024 set of textures. I set it up to render in Sketchfab. Most of the work was done in Blender with map baking done in Handplane Baker. If you haven't tried the software - you should, it works great. 2 things to remember are to scale up your Blender model to avoid artifacts in the bakes and always export into fbx - I had issues with the obj export.
