im not very good at explaining things so i drew you up something on mspaint.
now obviously it doesn't have to be exactly like this, because i did it in paint haha, but basically you get the idea, make the p's head bigger, fix the E's up so that its sort of one consecutive line, and with the S instead of having the lines go up and inward at the turns try putting them horizontally, that way it comes out cleaner.
in the end the only thing thats going to help you is to sketch as much as possible. thats all you really can do.
