You have a great talent for character design. Linework is clean, colors catch your eye, and the effort made by you adding a background shows you care more than most when posting a short joke. Personally I'd like to see you continue your art further.
If you need a break because you feel drained go for it, always turns out for the better when you set aside some time for yourself and return later on. When you do come back you'll have a fresh mind with new goals set for your future pieces and that's when art becomes fun again.
