This is not my best work but the only reason i'm saying that is because I focused more on shading and my items are small in the picture. In my opinion I could have done better with darkening my objects and making them look more

realistic and more like its poping out at you or it looks like you were able to pick it up. I also think I did good with the shadow but I shaded to much of everything. But I tried my best and soon will able to do better. All i need is a little practice.
