Hole In One

My seccond attempt at a terraspace piece...
I think I pulled it off, but dont judge too harshly...

Terragen took 40 mins and post processing ins PS took a single 15 hour session (with one hour sleep)...

Please comment & fav if you think its deserving...

---UPDATE---

Seeing a few people have asked I tought id run through how I made it.. I dont know how helpul it will be, just an account of the steps involved. *sorry is I miss anything*
(1) Played around in terragen for a few hours, using some DEM data of some canyon.
(2) Made the planet, which is a spherized rock texture with heavily modified difference clouds from PS above it... + some water..
(3) Went into Bryce and rendered a rock (the asteroid) & a fusion fire textured sphere (for the flames on the asteroid) ...
(4) With some cloudy brushes I made, painted the nebula and clouds above the terrain...
(5) Whacked it all together, adding stars (just high contrast PS noise) & lens flares, small gas clouds etc
(6) Added special effects, like the shock wave etc. (Shock wave is a sphere from bryce, volumetric texture, with changed perspective).

Hope that gives a rough idea.
