Short piece in four movements

What do you guys think about my relatively new piano work? I greatly appreciate your time listening to it and giving your thoughts! 

Thank you!

I. Way too sporadic for me. Too many atmosphere shifts. Extended harmony is cool, but doesn't have to be used in every chord either.
II. You could have fooled me that this was a continuation of the first movement. Having this one be different is important. Critics normally pan works that have similar movement structures. Playing around with a D was an interesting decision. 
III. Despite the chord sounding fine, this sounds like accompaniment... Try to avoid using too much iv -> i
IV. Best one here. Travels places harmonically and stylistically, but all feels coherent. The B minor chord, back to the G minor chord felt very awkward, though.
Cheers!
