RyomaNinja Concept Pieces-Need Critique

[RyomaNinja]

Hey guys!

This is my first post ever on Conceptart.org. I would like to get any critique on my work so that I can improve as an artist.

You should work harder to learn perspective and find where and how to put details (our eyes can focus only to one thing at time and that thing usually is the most detailed one, knowing that you can choose to add more details on the main subject). I like your work anyway
