Sketches from a Dark Matter

Welcome to
Good start to a sketchbook. Awesome stuff so far. Really liking the colors in each piece.
If you don't mind a little critique, the bottom one seems a bit on the monochromatic side. I would say try adding a bit more color other than the yellow an orange coming from the fire. Also the humans or explorers, they blend into the background a bit. I think the composition is good though. Just a few tweaks can be made to the colors. Other than that awesome start and I look forward to seeing more of your work.

No problem. I think you'll learn a lot a really grow as an artist. This site has helped me a tons so I believe it will help you as well. I think right now you should enter the Worlds Challenge going on. Contest are always great ways to improve as well as make some new friends. These pieces show me you have a good idea of what to do. Again keep up the good work.
