I've never done commissions for anything before haha but I suppose it would depend on what you had in mind. :)
Also thank you so much! I've been away from modeling for a couple months I usually swing in and out of it a few times a year.
I re-exported all the objects with the correct orientation, and textures applied properly. When I add the OBJ files to the zip, the textures seem to freak out but it should be as simple as applying the .mtl files manually in engine if necessary.
I added the main texture file to the zip as well. As far as scale, I'm not sure if it's fixed, but please let me know if they are still small and I will try and figure it out when I can! :)
