Ah, I see. Looks like you just need more practice then. Your goal with the zenithal is to effectively create your recesses and highlights before you apply colors, whereas from what I can see your model looks like mostly highlights after you're done dry brushing. You'll get better at it as you go. I'd try to have your recesses more pronounced next time.
Stole some random picture for reference of what I'm talking about. You should have clear dark spots and light spots for where your light source is hitting the model.
