If I remember, the problem with Stage 4 is that everything keeps moving so it seems impossible to make a single continuous map. There's the road with the desert background, there's the battleship that flies over you, then there's the helicopter ride with that alien mini-boss, and then there are the missiles flying toward the battleship's engine. That makes too many large elements which keep moving in relation to one another.
The best you could hope to do is a series of mini-maps showing the various sections of the stage, such as the initial desert chase with the ship overhead, then a single screen with the helicopter mini-boss, and finally the boss fight with the missiles and all. I wouldn't feel like doing it myself in his place.
But good work for all that you've done. I'm quite happy with Stage 6; I've always loved it when Contra does things Giger-style.
