Hi Eden,
Try using an Emission Shader.
Also, don’t worry if you don’t get the exact same look as your reference, just get something you like. When you get more experienced, you’ll be able to get reults closer to reference images. (And that is more important with photos and photo-realism anyway.) Nobody is going to compare your image to your reference (unless you are showing them both, next to eachother). Consider this a practice; it doesn’t have to be perfect.
