Hi!
I've been working a little bit in the lights and metal texture. I have made also a "complete" view of the lock.
Here's a detail of the different shadings I have tried. I think the third one it's my favorite.
Finally I've been playing with other shape for the lock, more readable in the "complete" view, but I'm not sure how it's been working with the "gameplay" view.
It will be great if you could give me your thoughts about this

Edit:
I have done some experiments with the color palette. I've tried some more realistic "metallic" colors and I not sure if I prefer that type of palette or a more fantasy one (like the one I've been using until now with yellow, purple, blue, etc)
I think I'm going with the "realistic" colors, but I will appreciate so much all your criticism with this particular subject.
Also I've thought in adding some "noise" to the metallic texture (like little holes in the plain surface). Here's an example
What do you think?
