I am a handicapped butterfly

Hi ,
I thought I did pretty good butterfly, but I was wrong again ! , now I got a chance to film myself, I realised that I do swim some weird butterfly. Things that I noticed myself doing wrong :


= Quick arm Exit before I even touch my thigh
= Arm Entry creating lots of splashes, not clean entry !
= L shape wrist/palm when exiting , why am I doing that , I wonder hmm





Please let me know other mistakes as well if you spot them :)
