I've had the pleasure working with @Brain on his game: Mr Boom's Firework Factory by assisting with some graphics as of recent. I'll post a link to his blog and gallery at the end so you can go and check it out.
Long story short, @Brain had a container which he could use but it was over 260,000 Tris and had 5 texture sets, and 4 decal textures all 4k each. I offered to optimize everything but realized the meshes were too messy so I ended up just re modeling it all while maintain most of the same look (structure wise - not texture). I then baked, re-textured the container, and added the decals supplied by @Brain.
The final mesh is only around 20,000 Tris, 1 texture set which is 4k (includes the decals within) which is a major reduction from the original.
I did two different lighting setups to show case the containers. The first is more outside cloudy type HDR, the second is a clear blue sky one.
