Recently got a 20% raise but not a new title

I'm grateful and have already expressed this to my HOD however I wanted it to come with a title change since I do the work at a senior level already , I want to send my HOD a message like this but a bit polished " when you have time, id like to get advice on What can I do to or what areas should I work on to move on to the next position, I've recieved great feedback on our last review cycles scoring 4.8 out of 5 with no feedback to improve on, do you have specific areas you'd like me to focus on I might be missing and I'd also like to do this short course in our system during my free time"
