I will only explain my last suggestions:
"Instead of put Annobon, could I suggest you split Zaire in West and East, and make possible attacks to Zambia? Only a suggestion. I think would be also good block attack routes from other continents to Uganda and Algeria."
Annobon route to Namibia is strange, since its much closer to Angola. But South Africa needs another route, so Zambia is the point. But Angola and Zambia are connected to Zaire, so no problem, only take Zaire too. Zaire needs to be splitted, but Congo continent will have 6 border countries, then lets block attacks to Uganda. I also think Maghreb doesnt need 5 attack routes, so I suggested block attacks to Algeria, but Niger is ok too.
The map is good, these are my last suggestions.
