Wow, you're improving fast! Some tips:
- If you're planning on OLL, look at the OLL's with two opposite edges oriented first. That set is usually easier and faster. Plus, if you solve 4x4, you can do OLL parity, and then a full OLL case, leaving you with a 2L-OLL at most.
- Try
downloading PPT (Prisma Puzzle Timer). It's easily one of the best timers out there. It saves scrambles, you can import scrambles, have scrambles that only scramble F2L slots/LL/PLL etc... It also generates better scrambles than CubeTimer.com. There's more information
here.
- In competition, you get 15 seconds inspection time. It looks like you sometimes use more than that. PPT has an inspection time feature, so use that to make sure you don't go over.
- Try to lookahead a bit during F2L. I notice you pause quite a bit, so that's a potential improvement. Badmephisto has a good video about that I think on his YouTube channel, so check that out.
- Join some forum competitions! It's a great way to compare times with others, and also, the F2L and LL competitions are great ways to practice lookahead and recognise algorithms quicker. Also, the Race to Sub-30 thread should encourage you to break that barrier.
- Your TPS isn't the best (I'd say around 2-3). So, try doing drills to turn faster (PLL time attacks etc.). Also, look at PLL videos from top cubers (Faz, Rowe etc.) and look at how they fingertrick each algorithm.
Also, if you post some more solves, I don't mind reconstructing them. The stats from reconstructions can tell you a lot about your solves and where you need to improve. Remember to post the scramble as well! (that's easy with PPT)
