Oil Painting Process Post #1

I really struggled with establishing a composition. Even now, I think my composition is ok. The colors are quite boring but cohesive, and the shapes are sorta interesting. My main concern is the lack of depth in the set up. The shadows aren't very interesting and the set up has too much negative space at the top and not enough at the bottom. I'm worried the flowers are going to be really hard to paint as well as the texture of the wood. I'm not much of a painter and am worried with how this will turn out.

I started sketching the still life and it looks very off. I think I will not draw the bag as it is in a weird spot in the drawing. My main issue is that I drew the objects at a different angle than pictured above, and I think I like it less. I really struggled with the angles of the cube thing as well as the pot. Hopefully the depth will come back once I start painting.
