I use F.lux all the time, and you don't even notice it until you turn it off, but I'm sure it's saving quite some eye strain when I compare it to how bright my screen usually is.

Main problem with it however though is that you shouldn't use it when you're working on art as it will heavily influence the colors. So it probably wouldn't help you too much.
However, you might be able to work on a piece with it on, and then turn it off at the end to change colors/contrast. Not sure if that's a good or bad idea.

Seeing that ^ just makes me realize how much more I should be doing to improve as an artist.

How were you able to get all those angles? Did you happen to have an actual skull around that you used for reference, or some website/program? (3D Model?)

They all look pretty solid to me as well, except the bottom middle one which is hard to read.

Dr. D I hope you like your's Im sorry I didnt encorporate your likes and dislikes into it more. Have some Happy Holidays though!

What!? 
You got like at least 4 things from my list there. And it's not like it had to be followed anyway. Anyways it's awesome.

Thanks so much, Happy Holidays.

Some really amazing pieces this year for sure.

But how do we start something like thins ? Do you begin in 1920+1080 and make a line and put color ? or do you begin with a really little picture, put all your shape and then make it bigger and add details ? And for the color how to know when to use those awesome blue and purple shadow ? It all look so clean, when I try it's awefull x)

Everyone works differently, but generally you want to work from less detailed to progressively more detailed. For a scene like that you may want to draw several thumbnail sketches for some compositions. After you find the one you think works the best, draw it out larger and then start deciding on where smaller details will go, still being a bit sketchy in the process.. and from there I would just start refining if I don't feel like it needs to be drawn over again. Colors can be changed at any time and you will usually find yourself tweaking things after the picture is finished. Some artists even draw entire pictures in grayscale and then only add color at the end.
