FEEDBACK AND RENDERING IMPROVEMENTS

After I posted the first rendered concept on facebook group page. Lockie adviced that the black, thick outline was unnecessary and also it was a common element of cartoony design. The problem was when I got rid of the outline, I got no feelings on what I coloured on since the colours would build up the boundaries by themselves, but it required more advanced skills.

 So instead of getting rid of the outline, I put it back into Illustrator to make the outline thin as much as possible (might thin enough to make it invisible)
Also I fixed some reflections to make it a bit more realistic.
