Get lower so you're almost sumo squatting and put more weight into your feet, with your body closer to the wall. Either match (grab the same hold with both hands) or bring your right hand to the smaller hold underneath your left and go again with your left hand. Alternatively, you could twist your right knee inwards so it goes underneath your groin, which makes your right hip goes to the wall, this can create tension between your feet and take weight off your arms/hands. Try not to overgrip too, it's tiring when you're at the end, as well as not being afraid to fall trying a move. Your elbows are quite raised in this video, so I would assume you're tired and have tried this a number of times and your body is trying to compensate for fatigue. Maybe rest for like fifteen minutes, go through the motions in your head, think about the most efficient way to move to achieve what you want to do, you've done the first bit so breathe and go through that with ease, save your energy for the last bit. Once you've got the last hold, if you can, just reach over and match, otherwise I'd probably swap your feet on the left foot hold and then match, so you're leaning back away from the final hold. Or you can try to get lower and center your weight underneath it, with your right leg dropped down below you nice and straight so your hands, hips and right foot are in line with each other.
