If you want a professional design then you must learn photo shop and illustrator advance tools and plugin. If you have a drawing tablet then you can easily design any type and short time. It's looking will be professional. You  to do try more and more than like you can see the YouTube video and copy their design. Then you will be a professional designer. I hope my opinion will be success your life. Thank you so much. See you...
