Hey!
From what I can see on the photo I think you might be putting too much product on. Try using smaller beads and press it out to the sides in each of the 3 zones.
When you first apply the bead to the tip or nail let it settle for a couple of seconds before you begin to press it with your brush. You will notice that the bead will ever so gently start to level itself and then you can do the rest.
The trick is to perfect your L&P application so that there is minimal filing afterwards. Be patient, you will get it spot on, it is just lots of practise. I've been doing nails for 15 years and I'm still learning, I still go on training courses and pay attention to other professionals' work to see where I can improve because that is the way this industry goes, it's always evolving so don't get too stressed out about not getting it straight away - you'll be learning for the rest of your career, it's amazing and so much fun
