Section 1 Yoshi swinging is tricky. Good muscle memory/figuring out a good pattern is essential. Sections 2 & 3 are straightforward. Bringing Yoshi to section 2 makes it even easier. Section 4 floor switching is straightforward once you learn to time your jumps correctly. Section 5 has two or three nerve-jangling sections which makes this very tense. Sections 6 is pure evil... Overall a great challenge!
