Your stuff is alright. Shapes are kinda basic and square, but that's not always a bad thing. I would suggest learning more in-depth shading techniques. You seem to understand the basic concept of shading, but it looks like you pick a color and just lower saturation until it is lighter, try using all the sliders when choosing a color rather than just saturation. Also when your making all those swords, don't just use one color for the blade and handle, even if the handle is a darker version or the color. There are some good tutorials on YouTube about shading and all that, try looking up hue shifting and complimentary colors and that sort of stuff.
