The contrast of the black and white parking lot picture really left a impression on me. Really impressed.
The background is not focused so all the attention goes to the muffin standing out over the background and I really like that. It's done from a really cool perspective.
I think your photo of the muffin is actually incredibly impressive, it's a difficult subject to make look interesting and you did just that. By giving in the context of the bite and providing foreground and background you went above and beyond in terms of creating interest around a piece of food.
I love this picture, I love how it is at a different angle and causes the eye to focus on what is going on in this photo. It is very artsy and I like how it isn't centered either, causing you to focus on different aspects in the photo.
Write something about yourself. No need to be fancy, just an overview.
