Help with routine (splits)

I want to know if my current routine for getting my splits is good or not, and maybe some advice on more dynamic stretches that I could include. This is my current routine:

  • Jumping jacks (30-60s)
  • Butt kicks (30-60s)
  • Hip circles (30s/direction)
  • Leg swings front to back (30s/side)
  • Leg swings side to side (30s/side)
  • Standing split hamstring floss (30s/side)
  • Wall calf stretch
  • Forward fold (L leg)
  • Forward fold (R leg)
  • Forward fold
  • Low lunge
  • High lunge
  • Lunge with elbows on floor
  • Kneeling hip flexor stretch
  • Figure 4 stretch
  • Laying down, lifting leg up with a band
  • Pigeon pose
  • Half split
  • Frog pose
  • Butterfly stretch
  • Split with pillows
  • Attempt unsupported splits
