You are not alone kuya! Just want to tell you that I am also experiencing the same. Keep up with this great idea of just drawing what you are thinking. Sometimes we are having a hard time looking for the best photos to look for to the cover photo of our blogs. And yet by doing this process, it won't be hard anymore and all the things that you have in mind is just the perfect cover for the project you are going to post.
Hats off!
