Lmao that dog is so cute! I think you did a great job. There is a little too much space at the top, but the picture is crisp! I can't wait to get my softbox in Good job!
There's no way that's a real dog... it's a statue?
Great sharpness and clarity. Dust is gonna be a pain with that setup, you can see some on the bottom. I'd keep a can of compressed air around to fight that.
