It get better with time. You can start painting, training on visulization practices to go forward faster. Its a part of our brain that need to be stimulated in order to develop. Some is born with it due to many reasons but for sure is that they have earned it trough lifetimes. For me it was very frustrating and took enormues of mental energy. With void meditation it get way easier. And i have noticed that you have a individual style of visulization, mine is cartoonish.
