First one does look best. Just remember that when making the edits you must take the size of LttP Link into consideration. Make sure he'll be able to fit through the paths.
As for this and OoH, I find it better to work on them at the same time. Since all the maps are done in OoH, all there is to do is programming. This game still needs maps done, which I can also do easily. Some days I'll do one, some days the other, and some days both if time allows.
