i use to be worst(a 200pp player) than this 1month ago but i found out the problem and fix it with the help from other player, and now jump to 2k+ pp in few days by following those rules.
1)as evil ryu you want to be in effective range and try not to back off(try to maintain spacing) if you back off evil ryu= no pressure at all because it seems everyone is just scare of his cr.mk or jump in. ideally you want to keep a distance where you can jump in and land a kick on them when they use fireball. if you back off in distance they will just abuse their fireball or do anything random. keeping this distance also allow you to AA effectively when they jump in.
3)your defend need to work on.
4)work on anti air
try using hp hadoken for fast speed hadoken and switch in between lp and mp etc.
focus atk through fireball or take small step and defend when they throwing fireball until you are in effective range. no point jumping in if you cant land a hit or endanger yourself.
number 1) spacing is most important and following this make me improve alot. evil ryu with no pressure is useless.
