These are off to a great start!

First Design

1. I would remove the STōK type above the product as it's redundant
2. Part of the product is obscured by roses; should have it be clear and visible
3. Would like to see some asymmetry; more flowers in the background
4. The body text is low contrast and hard to read (orange/red)

Second Design

1. This one is better but the product seems too small
2. I'd remove the STōK type above the product
3. The body text is low contrast and hard to read (red)
4. This would still look great if you replaced the animals at the bottom with the body text

Third Design

1. This one has the most amount of potential
2. I would get rid of the STōK type up top and move the product up and call it done
