Quick question about Yale sculpture portfolio!!

[arte]

All the other departments require your portfolio to have about half of works from within 12 month and rest from within 3 years. 

But sculpture department doesn't say anything about three years thing. 

Is if okay to upload works from before?

+ I uploaded 15 images and the review section says it could be a potential problem. 

is 20 images required?

Please!!

I uploaded 20 images all from the past 2 years.  It's probably a good thing to show you're constantly generating work, but quality over quantity id say takes precedence.
