It can only "look" like something if you have a mind.
Different animals have different visual capacities and things look very different under a microscope or at the atomic level. There is no independent way of something being in the world.
It seems to me that you are claiming that any perspective on anything is dependent on external input but that seems trivial if true. It might be but it might not be. But what different perspectives require is a mind. A coin can appear different from different angles but these are not part of the nature of the coin.
An unconscious object has no perspective.
I don't see how belief in an external world rules out belief in an internal world. A dream is a clear example of something internal or mental. I have vivid dreams which are photographic sometimes with sounds. If the dreams are based on the external world then they must be based on stored memories of it not immediate access.
To have rich veridical-truthful access to an external world like we seem to have would require immense sensory apparatus and conscious access to the product of this sensory scheme. That is to say the more accurate we believe our experiences to be the more sophisticated our means of capturing details of the external world must be.
I think Descartes thought God gave us honest perceptions because God is not a liar. Now evolutionary theorists claim that we must have accurate perceptions because they favour our survival so would have been selected for.
However I think as I said earlier that only an explanation of consciousness can resolve the issue of the validity of our perceptions.
