Perspective?

I'd really like to tell the AI to use a perspective and scale. I have tried for a long time giving text like "using the perspective, orthogonal, dimetric projection and 2D. viwer is looking down on the image from above" It kind of understands, but I'd say it's 1 in three and the more specific I am the more confused it gets.

so how about commands to do with the perspective go within some punctuation, for example

*orthogonal, dimetric projection, 2D* a house by a lake with two threes on a suny day. 

maybe this sort of thing has already been discussed and someone can point me to it.
