i need help bad from anyone who is willing to critique my work. I will post here as I can. I really want to become a much better artist, but my basic skills are pretty lacking.

Any advice you guys can give would be great.

the surface is supposed to be really shiny and reflective, one light source is white while the other is yellow. the white light source is much closer. I tried to capture the reflections, but I couldn't figure out how to make them look like reflections. It kind of looks like a crappy design on the bottle to me.

I spent way too much time working on the cap, but I like the way that turned out.
