I use screenshots with everything in 3d, usually the creators use sprites on images since it is easier and many times the image seems to be flying over the ground. But from the little experience I have, I think it is much better to do it that way since it consumes less time, you do not worry about a problem with lighting or moving everything within a 3d map. In short, do not do the same as me unless you have a team to distribute the tasks. I always complained about some games that were less elaborate but they still do better than me haha
