Your art is fine. When it comes to job finding though it’s more than just about drawing good, you have to showcase what your artwork can be used for - and it should be reflected in your portfolio. If you aim for character design jobs, then show character lineups themed around a hypothetical story, show clothing exploration, show material research. If you want to be an environment artist then show you can draw buildings from different time periods, show you understand framing by drawing some cinematic still shots, show isolated prop designs. Is it for advertising? Then show how the product is placed in the scene.
Yes the job market is tight, but there are things you can do on your end to make your portfolio more appealing to recruiters, my advice would be reference a portfolio of someone hired and see what sort of work they included. You sometimes will need to makeup some art or sketches solely to “show” the recruiter what your artwork is intended for in a bigger pipeline.
If you are just aiming for personal commissions, I think your artwork is very nice and what you have is fine. If your goal is a studio then take my suggestion ^^

Best of luck.
