Hi! You’re doing a great job exfoliating the sides and effectively removing dry skin. I can see that you're using a high RPM, which is great, but be sure to apply light pressure and focus on smaller areas of the nail to prevent over-filing. 

For the center exfoliation, it’s nice to see that you’re now working at a slanted position. However, be mindful of the angle—it should not be too high or directed towards the client’s nails. Although your position is slanted, the angle still seems slightly off, so try adjusting it to ensure a more controlled and precise application. 

Regarding the base coat, make sure you're using one designed for both building and protecting the nail. Some base coats are too thin and may not provide adequate support even after curing. Also, be cautious with the cuticle area, as I noticed slight irritation in some spots. A gentler approach may help prevent this. 

Your gel color application looks great! Just be mindful of product accumulation on the free edge, as it can create a rounded appearance. Additionally, refining the free edge a little more will help achieve a smoother and more even shape. 

Overall, you're making excellent progress—keep up the great work!
