This was done for "Mesh Modeling Fundamentals" course from "Introduction to Blender" learning flow. Since this was done in Blender 2.8 and sketchfab doesn't support it, I can't submit my work over there and finish the course (changing file format doesn't help), so here you go.
Nice lighting.
aanlymoi glad to be of help and that it worked :)
ssmurfmier1985 This actually worked! Thanks so much for the advice.
Looking good aanlymoi This scene is pretty simple and ! I don't see much to improve here. Time for the next course and exercise!
Good job!
If you export your file in FBX format, then you can upload it to Sketchfab :)
