The acrylic nails are not too bad, I will agree with what's been said and say the fanning and balance on a few sets need to be looked at but over all, pretty good. I will totally agree, the almond shaped nails with the 3d flowers are the best set out of both the acrylic and gels, well done on those ones, they do look beautiful I must say
You asked for opinions on the gel nails, well I will be honest and say that there is not many sets there that I think I would be happy with as a client I'm sorry to say.
They all look like tips have been used, they have all be placed way too far back and look stumpy, they are all not even (different free edge lengths and shapes), some have the tips placed crooked and many have wrong sized tips being used (pic French Butterfly 2 especially on the thumb), many of them fan and looking at the line of light, the apex is not placed evenly across all nails and some are dippy and lumpy in places.
Had an cover powder been used to extend the nail beds, I think they would have all looked much better.
Some time needs to be spent doing some serious practicing to refine technique I think and the gel nails will improve greatly.
Sorry if this all sounds harsh but there's no point in not being truthful otherwise no improvements can be made.
To me, it looks like the person doing the gel nails could be very new to nails and just needs a load more practice.
