Hi jnails
For 9 months in the industry these are good - here's a few pointers that should help you improve.
Your side walls follow the skin fold, not the nail - look on the thumb it is fanning out. You need to file straight down the full length of the finger ..
Apex is central, but far too high, which is why everyone says they look bulky
For this client a more appropriate shape would actually be more square than the round you have used... (it should mirror the cuticle line shape)
Also this round shape has removed your lower arch - you can see this on most on the index of the right hand, where the nail looks like it comes up off the finger, this should look like it extends on a gentle curve from the finger.. there is a great tutorial on here about lower/upper arches. have a search for it.
good luck and keep practising
