I'm not going to rate, as rating = fail.
Instead, i'm going to CnC!
Prayer, really messed you up, you should have stayed one prayer, because it keeps your combat at a low level, and tbh prayer isn't worth it.
How you can improve;
Since you already have prayer, do desert treasure, and get 82 magic for Ice Blitz. Dds flood + Ice Blitz + Rushing them (meaning, attack suprisingly), will usually kill them before they have a chance to fight back.
Keep training your strength, I would recommend you train range in your free time for the Hit Points level, it's worth it.
