new youtube design

Just started channel and its been getting lots of traffic even while i have no page design, but i have great professional engaging content. How can i spice up my artwork. Whats the right way and what should i advertise. here's my channel content, if you have any ideas from what page represents...

Am I the only one who's noticed that youtube has changed its channel banner size along with the layout of youtube all together? It took me 6 hours to make my banner, mainly because of sizing and im a perfectionist and now it's cut off and I have to redo it :crying::crying::crying::(:poop:
