The Africa map seems perfectly plausible to me with a different land grab in Africa. If you told me this was a map of Africa circa 1900 it would look very reasonable. Britain takes east Africa, France the south east, Ivory coast territory, and Algeria while Portugal gets that long coastal strip down the south west. Belgium still gets the much of the Belgian Congo even and Spain gets Morocco. The rest is divided up among themselves and the other minor European players. Portugal has done well in this timeline but other than that seems reasonable (perhaps the Iberian Union lasts). The colonial African borders were largely arbitrary anyway.
