Please Help Me With A Packet Tracer Design

[Hudson86]

I'm doing an assignment to design a network for a company in packet tracer. There are 2 branches one (on the left) uses a hybrid of Ring and Tree. Another one (on the right) uses a hybrid of Tree and Mesh. 
Plz help to check whether there are the right topologies of these two yet. And I don't know why after connecting 2 routers, I checked to connect between 2 branches it said failed.

My packet tracer is below.

Thank so much for ur help.

Hello,

I have opened your file, and there seems to be connectivity between both branches. What specifically can you not connect to, and from where (which source to which destination IP) ?
