There are definitely some perspective issues, the most apparent one to me is the tabletop stove. The back edge is sitting flat, but the front edge is clawing at the table because it’s not going to the left vanishing point. I also think that the environment backgrounds you are sketching around your main object are clashing with the style you are trying to achieve. That stove would look much better if you left out the pots and pans and rendered the top with marker and maybe added a vignette behind it (but totally not necessary). I think this will drastically improve the way your sketches appear because they aren’t too far off.
The only other thing is your line weight is pretty shaky! loosen up!
Look forward to seeing more!
