It looks artificial every time I contour;;;

I heard that contouring can give a more sophisticated impression, so I've been watching videos and practicing, but the more I do it, the harder it gets.

What I want is natural-looking shading, but every time it looks too excessive or patchy and artificial.

In particular, I want to tone down my forehead and jawline, but when I apply shading, my forehead looks heavy and my jaw feels like it actually looks wider. I've been trying hard to shade my cheekbones too, but it just makes them stand out even more...

Even if I blend diligently, the product clumps together, leaving distinct boundaries, and then it all vanishes over time.

Is my dexterity the problem?!

Also, my skin seems to look duller when I contour, but I'm not sure if it's a problem with the color choice or the way I apply it.

Is there a way to achieve natural yet defined contouring?

If you have any tips that even beginners can easily follow, please share them along with the product.

thank you
