Hey Kevsan, great job all over. Honestly I think there is too much black color in here and you could've added a bit more details all over around those parts. Don't be shy, they add tons of information and coolness all over
Thanks for the critics! Yes, I totally agree! The reason why it is all black and dark is because I painted it in greyscale at first. It made me a bit lost in the color scheme and the darkness of the painting, cuz it was my first attempt to do this method! But thanks for pointing this out and I'll will try to follow your advices in my future works!
