picture is a bit fuzzy.
but i'd say your work is really coming on, ive seen real prgress in it since you started asking for critique.
so as i say pic is a bit dodgy, but...
smiles are nice and deep.
tips do seem out of balance with nail bed area, a coverage pink could elongate the nailbed and then your tip area could appear a little shorter and give better proportions.
they also look a teeny bit wide and flat. this could be rectified by keeping the file perfectly parralell to the side walls when finishing and contouring the nail more with the file or preferably your brush during application. though this could be the photo because it cant really capture the true 3d nature of a nail. sometimes i have done nails i'm very pleased with but on camera they didnt look so hot.
