Beautiful photo! I love the objects you've chosen here, the snail and flowers create an interesting contrast, and I also love that you chose a simple background to further draw attention to the foreground.
First of all, the colors are lovely! The darker blues in the background make the flowers "pop," and the darker shades of the snail also creates some great contrast. I also like how the light comes in from the right side and sort of illuminates a path of light. Excellent work there!
The shallow DOF was a great choice for this photo, but I do wish that there was a bit more focus on the flowers themselves, as they look pretty sort in comparison to the snail. I noticed the snail right away because of the sharp focus there, and perhaps having a bit more of that on the flowers would help. I like how you've got the flowers in the back blurred out, though! c:
I also don't mind that the snail is cut off in the corner - I thought of mentioning something about that, but I realize it better positions the flowers in the rule of thirds and whatnot, so great work on being able to see that!
