I never check out the critiques section, and I am not claiming to be an expert, but I have noticed a couple of things;
At first glance they look nice, and for an early attempt they are pretty good IMO.
However, it looks like you need to work on your application and blending around the sidewalls and cuticle a bit more - they look a bit bulbous. I've noticed that the line of light doesn't look too off, which would suggest they aren't lumpy on the surface. I've seen alot of lumpy gel overlays, people must think 'just slap it on and that's fine'
yuk!
I've never used Brisa, but with the gel I use I can pretty much create a seamless border with barely any buffing/blending, but you will get the hang of this with a bit more practice, providing you are using the correct techniques; It's no good practicing the wrong way lol. :smack:
The little finger looks quite thick to me, the thumb looks about right for thickness, but looks like there is a dip where the smile line is, this could just be the picture though. can't see a side view of any of the others.
Your smile lines are a little bit inconsistent, but again, with practice this will get better. I like to make sure I get right into the corners with my french application, otherwise it just doesn't look as professional i don't feel.
Gel can sometimes be tricky to get the hang of if you're used to L&P, but good on you for posting your pictures!
