Well, its well said that "Your First impression is your last impression" and the same applies to your videos. You need to give a unique title and thumbnail to your video because most of the users look at the views of the videos for the one to be selected. If you are beginner, you probably would not have enough views so you will have to focus on your video title and thumbnail.
Your videos title should be very unique and also relevant to your video content otherwise it will not gain enough watch time. Watch time is very important as it shows how viewers react to your videos.
You can create your youtube channel art with photoshop, snagit and it should be in square and good resolution.
