freestyle,butterfly technique help please...................

hey guys, I am looking to improve my 50 free and 50 fly performance. I have a best of 24.5 in the 50 free LCM I don't know what my time is in the 50 fly but I am pretty sure that comparatively its better then the free. Anyways I have recently started to do some serious strength training after ande told me to. I have already improved my swimming times. I believe I should be able to go a looot faster than this. My realtive strength(strength to weight ratio) I think is as good as the elite swimmers if not better ( I am not joking). of course just being strong doesn't ensure that someone will be very fast in the water. One also need great technique, which i think is my main problem........ so guys I am posting some clips of me swimming...... I would like your comments on what I should do technique-wise, training wise to swim to my best potential............... www.youtube.com/watch www.youtube.com/watch www.youtube.com/watch www.youtube.com/watch My goal is to swim 50 free in less than 24 seconds before 2014 and in the fly........... well I don't know possibly faster than the freestyle ( comparatively). thanks in advance............................
