Line on the map seems to be going the right way. Looks good to me. Don't forget to check Notams as late as poss before you go because you can bet your bottom dollar that someone will be flying a kite no higher than 500' along your route or someone will be launching balloons, fireworks, witches on broomsticks, SAM's etc.
I notice you are flying over Stapleford ATZ. Ask your instructor about calls to them.
I take it CAS considerations are a given.
Enjoy it, your first XCs are great! Slipping the umbilical of the circuit and all that.
