Thanos And Mistress Death By Pant Inked Small By G

Hi.
I'm not very eloquent today, so sorry if it's not very well written or as detailed as I'm used to.
Here's my two cents: The palette is fine. The problems I see are: The blue colour of Thanos and the blue of the bg are the same, which doesn't contribute to separating the two planes.
*You use the same colour for all the dress, for instance. You should use more colours for the same object. Look at mine, as an example. I used yellow, red, green, and touches of hot pink.  
*Try not to use white for lights and black for shadows. You can choose complementary colours, or variations in temperature. Look at this awesome example: 
*Get rid of blurry brushes. Use sharp edges for cast shadows. Show some contrast.
Finally: Variation is the key. Same bruses: boring. Same colour: more boring. Look at this nesskain.deviantart.com/galler…
You'll feel like your work is the worst ever after looking at this guy's gallery. I do. But you'll see what I mean.
I hope it was useful!
