I know the picture isnt the best, but its the only 1 i have for now :(
All you need is a nail file, black nail polish, yellow nail polish and clear.
File and shape nails into a rounded tip, remember only file in 1 direction, never back and forth as it will cause your nail to split
Paint nails yellow, give a second coat for extra dept in the colour
With a really steady hand make 3 black lines across your nail, if you have a nib on the top of your brush it'll be even easier! Coat in clear nail polish for extra shine
My sister drew wings onto my finger to give the example :D
