School concert logo

Hello, I am looking for someone to help revamp a loo design I have been working on with some school students. It is for our school concert. The show is titled Hamilton Public School is Grateful. I have attached the current design. I am happy with what the students have done so far, but I feel it is lacking that wow factor! We were wanted the 'grateful' to be a play on words- 'great' with the 'e' crossed out and the correct 'e' added after the 't' like to fit in with the school theme. I would love the 'grateful' writing to resemble a childs handwriting and this to be the focus. Maybe the letter size bigger than the Hamilton public school. As I have only scanned this hand drawn design in, I am wondering if it can be made more vibrant/bright etc on a computer program? With little experience in this area, I am open to ideas and suggestions. Kind Regards Hayley
