Looks good but, the concept of the Ark Angel transforming into a robot seems a bit flawed on a practical stand point. For starter, the transformation gives them no advantage. After looking at that picture, it looks like the synchro cannon is fixed on the back and doesn't swivel like the main cannon of the SDF-1, or detach and become a gunship. So it means that the main cannon is only useful in ship mode. In the end, it would only make the Ark Angel as a big target and put the civilians in danger.
