You dont say on your profile what system you are using or who you trained with. For us to give proper feedback it would help us if we know all the nitty gritty about you, how long you have been doing nails for and what system.
Also if you want good feedback its better to have a barrel shot and side view shot rather than just the one straight down.
That being said however from the picture you have posted I can give you a little feedback but please dont be offended..well done for posting :hug:
They look hippy, when you file the sidewalls yyou need to keep your file parrallel to the side, it looks like when you are filing you are angling the file round giving the nails a hip towards the free edge.
They also look quite thick but without side view I cant really say. This could be Too much product or you didnt file the tip thin enough giving them a bulky appearance before you even start applying product. The tip should be filed really really thin so that the application of product wont need to be too bulky to cover iykwim.
The smile lines are not too bad just a bit off on a couple not consistent with each other and also placed a bit too far down the nail bed you should use the fingertip as a guide to where to place the smile line.
When you are finishing what grit file are you using? You need to go up in grits to refine the surface start with a 240 file then work your way up to a finer file, that will help remove the scratches, then you can buff in some cuticle oil to bring to a high shine.
If you really are lacking in confidence it may be worth booking a one 2 one with your educator or maybe even booking a conversion course.
