OK I'll be the first to comment.
While I applaud you for attempting to light source the box, spirits, and flames, (I personnaly won't even try it,) to me it looks more like mistakes than light. I think the issue is it is too heavy. It needs to be done with very thin paint and built up in layers over time.
That also leads me to say that it appears you need to thin out your paint more.
Also, shading and highlighting will do more to improve the models than attempting light sourcing. Your skin tones are flat, especially on Pandi.
But, this is not only a negative post. I really like where you are going with these pieces. I think you have the start of some good models there. a little more practice, thinner paint, and some more shading/highlighting will really help.
Good luck, and continue the good work.
