These are lorax nails. now i am terrible at doing nails but i am guessing that you would need these colors or something close to them you really just have to have a steady hand trace around the character and tree. but i haven't tried it but in my opinion the lorax looks farely easy.
"Today, some Christians are content to merely exist until they die. THEY DON'T WANT TO RISK ANYTHING, TO BELIEVE GOD... GROW OR MATURE. They refuse to believe His Word, and have become hardened in their unbelief." ~ David Wilkerson
