Your dog is SO cute. You worked SO hard on this, you're one of the few people to fight your way through to making most of your design on Photopea and not just by hand. Thank you for working so hard. Like I've been telling you all year (in Painting class too) you are too hard on yourself. You're very talented AND work really hard, but you're your own worst critic. You have to find a way to get over this perfectionism. Don't hate art because your artwork doesn't meet your own expectations every time. You're already good, but we can all always get better. Try focusing on the process instead of the product so much. Let yourself enjoy the challenges instead of getting so frustrated.
Aren't you amazed by that yellow to orange fade? It really looks like explosive fire and makes the "cap" stand out with contrast, emphasis, AND radial balance. Thank you for pushing yourself and working so hard on this, it looks great.
I wasn't sure at first how the pop bottle would turn out, but this is really fun. You did a great job drawing the Sprite and I love the patterns in your background shapes. I even like your pig.
