Incredible work! You’ve got such a great sense of high energy in this piece!
When I’m stuck with art, I either pick away at small stuff on art pieces, but most of the times I feel like it’s a good idea to just take a break! Take a day or two off thinking about art, and then come back to it fresh! The drive to do it comes and goes sometimes, and trying to force yourself back into it usually only makes things worse.
I hope this helps, stay strong my dude! You got this!
