"r, z, e, s, x" is a mixed group.
The video below shows you how to join "s" and "e":
The writer's "s" slants far forward.
Notes:
R
Notice that lower case "r" is the bottom half of a capital "R"
S
Also notice that lower case "s" is the bottom half of a capital "S"
E
Notice that "e' is not a smaller version of lower case "l". After the middle bar, your pen should go around like a "c".
