I Like Your Work
Your a pretty solid artist, and you are drawing a lot of things I grew up with so that adds even more bonus points, But I feel that these power rangers you have been doing lately are just below your level.
It's mostly your lack of shading and line weight. They are just flat and I think that makes them a little boring. I know these are meant to be wallpapers, but I know you can do much better.
You could turn these in to real epic pieces...
