I love the blur you add on the man to show motion. It looks really cool. And you did a wonderful job on the portal. Especially where it looks like a beam of lightning struck out and hit the ceiling. Awesome.
Don't worry, my ego is not that big, and the purpose of exposing my gallery to better artists is to get some constructive critics and advices which will help me become better. I'm a self taught artist so all the result of my gallery is the result of hard work and a few good advices, and I know still how long the road is for me, so feel free to comment
I saw your work my general advice would be: work globally and not on the details a good illustration is about lighting/forms/shadows/textures/composition you have a tendency to paint like you draw (you should block-in the colors in bigblobs ,not draw with color) and overwork the details... so it all looks flat with no life.try to study anders ZORN,sargent ,monet,richard schmidt and how the impressionist worked.
squint your eyes.
also (saw that in a darthmaul painting)work your environments ,for exemple the rocks are completely horrible there,so use references like photos and study how it works.
study anatomy as well,painting humans is really hard.
