Changing pencils would make a massive difference.
But my opinion differs in that I think you should actually get a harder pencil, start your sketches with a 2H and working towards 2B as the concept gets more refined.
Not seeing much of salvador dali in your work, he was a surrealist, hyper realism, turning realistic scenarios/subjects on their heads.
If I had to make a correlation, you have more Joe Fenton in you, check him out.
I think you need to move away from these classroom doodle type sketches though, changing pencils as you work would give your lines alot more "intent" as it were, keeping them rough and sketchy, but looking like you actually meant to draw them the way you did.
Sketch in 2H and refine with a 2B and only use a 4B for the extreme dark bits.
And try to stay away from hard outlines.
Also, lines and dots arent the only way to shade with pencil, holding the pencil on its side and using the side of the lead, gives you a broader stroke more akin to painting or charcoal, although Im not much of a fan of that. But adjusting your angle does give you more options.
When working with 2B and 4B, you can also use your finger or a putty eraser to smooth and smudge the shading.
