You are in the range where there will be lots of conflicting opinions. In general - you look good.

Your elbows are bent. Good. But you need a fair amount of power to keep them that way. If you moved your hands to the drops would your back/head position change? They should not.

If you can - open up the hips - a less acute leg/torso angle, such that your hips and lower back are more upright and the bend in lower in your back. If you could slide forward on your seat (slide do not adjust) without your head or shoulders going forward that would be the idea. Easy to ask about, hard to do.

Your seat may be too low.
Your bars maybe could be lower, again based on power you can put out.
