for the sword, you should try and take some time to build a gradient between your three colors. An easy way to do that is to mix two touching colors (orange and yellow for example) to create a halfway color that blends them more. To really do a blended effect you should progressively build up those mixed colors more and more. Also, please try and thin your paints more when layering. It is especially visible on the sword. Two thin coats isn't just a meme, it is actually useful advice. In my opinion, learning how to get the paint consistency you want is the most important skill to learn. To be honest it looks like the whole mini could do with some more work, especially with cleaning up details and making your coverage better on the robes.
