Well, if it's a stellar black hole, the schwarzschild radius shouldn't
be more than a few hundred km and you don't want to see that as a disk.
If it's a super-massive black hole, you don't want to be close enough
to see a single star falling in as a large disk.

But in that case, why is the ship distorted too?

Mmm, too true... ;-)

The vortex effect add a lot to the picture.
I find it well balanced in that view. Congratulations

Fascinating discussion, really, but I feel obliged to point out that any
resemblance to real spatial phenomena is entirely coincedental! :-D
My sum total knowledge of black holes consists of stuff I've picked up from
Star Trek and the song Supermassive Black Hole by Muse.

Let's just say that at that distance from the hole, that ship is not leaving
again, unless it can travel at a speed very close to the speed of light.

Very nice. I'm still not sure about the distortion ring around the hole,
though it looks better than before.
A suggestion for more 'realism'. Red-shift the colours slightly based on
their proximity to the hole.
Light travelling near a black hole looses energy, in addition to being bent
towards the hole. This loss of energy results in colours being shifted down
towards the red end of the spectrum.
I don't know how hard that will be, or how good it will look

Nice indeed! Much better.
I agree with Gail about the ring. I imagine that the black hole would be
totally black.... Now, where did I read that black holes would have a
slightly bluish glow...??? I can't remember.

Makes you wonder what happens to the light that comes from a point
between us and the event horizon.
