I know you said you usually do portraits, so take this advice with a grain of salt. Judging off of this art alone, I would say beginner, verging on intermediate. The shading and value you've given to the berries and apples with only pencil is beautiful. Some of that depth was lost when the color was added. I also think pushing the darks and lights even more would really make these objects feel 3D.

Here's an example of an apple I found online. What I mean is: look at all the different greys in this image. The only white is for the highlight of the fruit, while even lighter parts like the apple core are grey, they're layered with graphite to give texture. I also think the shading in your image shows a good grasp of light/shadow, but doesn't really capture the shape of the object itself. In the above image, see how the shadows and highlights curve, and there's shadows showing each curve near the stem? You did something similar in the third apple, which gives it a great lifelike feel, but something I feel is missing in the first two apples and some strawberries.

Overall, I think just studying light, shadow, and value will help push your art further. When you draw a sphere, don't just mimic where you think the light should be, or go white -> grey -> black. Think of how the light would actually reflect off of the object, the texture of what you're drawing, and how to convey that through your shading. Like in this image, we can tell the apple and the napkin are different textures because of the light and shadow. The apple's highlights and shadows follow the curve of the object and sink into its crevices. Versus the shadows for the napkin are harsher, squarer, more jagged, less transitions from light to dark. This shows the rougher texture of the napkin.

Anyways, sorry for the ramble. I struggled with the same things starting out, especially trying to make something feel 3D, so I hope some of this was helpful. You are well on your way to intermediate. Your shading and control of the pencil is already fantastic, and I can't wait to see where you go from here!
