Nice model! The only things that I would not agree with are as follows:
1.) The seals should all be contained within the seven year time-line and not outside of it, as the first seal is the revealing of the antichrist, the rider on the white horse.
2.) The Male Child is a collective name for the 144,000 who are caught up to God's throne at the middle of the seven years (Rev.12:5)
3.) The saints do not reign over the 144,000, which are the first fruits out of the twelve tribes of Israel, who will not have defiled themselves with women and in whose mouth no lie will be found. The fact that scripture states that they sing a new song that no one else is able to learn (Rev.14:3-4) would demonstrate that this group will not be subservient to any other group of saints.
4.) Though there must be a renovation of this present earth when Christ returns to end the age in order to live during the millennial period, scripture has the new heaven and new earth being created after the millennial period and after the great white throne judgment. Also, I personally believe that the new heaven and new earth will be brand new, as in novel, never exiting before and not a renovation of this current heaven and earth. In support of this, John says that he sees the New Jerusalem coming down out of heaven from God. Regarding this, there should be no controversy in recognizing that the new Jerusalem is not a renovated version of the current city of Jerusalem, but is completely new, having different dimensions and is much, much, bigger and is made by God. Therefore, the new heaven and new earth must also be completely new, for they are all said to be new.
5.) The New Jerusalem does not come down out of heaven until after the millennial period and after the great white throne judgment, when the new heaven and new earth are created. During the millennial period sin will still be apart of the those who are mortal and who will be repopulating the earth. Therefore, God is not going to bring in the new heaven, new earth and new Jerusalem while there are still people existing with the sinful nature. The new heaven, earth and Jerusalem will come after all have been cast into the lake of fire and all that is left are the righteous. The following must all occur before the New Jerusalem comes down from God out of heaven:
In
Revelation 21, the recorded history of man is at its end. All of the ages have come and gone. Christ has gathered His church in the Rapture (
1 Thessalonians 4:15–17). The Tribulation has passed (
Revelation 6—18). The
battle of Armageddon has been fought and won by our Lord Jesus Christ (
Revelation 19:17–21). Satan has been chained for the 1,000-year reign of Christ on earth (
Revelation 20:1–3). A new, glorious temple has been established in Jerusalem (
Ezekiel 40—48). The final rebellion against God has been quashed, and Satan has received his just punishment, an eternity in the lake of fire (
Revelation 20:7–10.) The
Great White Throne Judgment has taken place, and mankind has been judged (
Revelation 20:11–15).
