Multiple user portfolio gallery with each member subdomain personal portfolio

I am building painters community with their portfolios and one general gallery where all painters photos are sorted with rating or likes.
Could anyone help me with that? there is no ready to use plugin for that, but must be a solution.
NextGen gallery has voting plugin but it’s not very useful for adding pictures by members and they should have their own portfolio pages located on subdomains. Each image of each author participates in general website gallery, where voting and painter signature take place.

I’m very thankful for any suggestions or thoughts on how it could be done.
