I'm trying to create a crystal lit lamp light effect radiating from this crystal lamp, but the things I tried looked pretty bad... So bad I didn't even save any of the attempts for you guys to see!

Trying to get a bluish-green light similar to the lights found in this image:
(NOTE image is not mine, and unfortunately I can't name the artist as it was sent to me as a nameless inspiration image). Trying to get a cold, industrial feel going for this steampunk project.
Any ideas? I didn't even try doing it with pixels and instead messed around in photoshop, but still couldn't get it to look right.. Is this possible in pixels?

I'm trying to draw a puddle on some cobblestone, but it is looking awful and I don't know how to make it any better. The puddle doesn't animate (so no ripples) and it can't have reflections in it because it is to be used randomly throughout a game's city. It should just be a leftover puddle from the previous rain. Because of this I am having a lot of trouble making it clear it's water... Any ideas?
