thanks for your critiques
some explanations
i only had 2 days for texturing 1day for rendering 1/2 for compositing
my fault
the face of the astronaut was modeled but it took too much to texture
the background does not match the reflection
my mistake
wanted the helmet/reflection to appear bigger in the final img but then i had to make bigger textures = render time up
soft shadows not so soft
not enough details
…
bottom line i really wanted to finish the challenge with a decent image
again thanks
