17/1: Sounds very good to me, I think you captured the risoluto mood very well. Also dynamicwise, there are accents and softer passages. Maybe on the e flat major section something more could happen towards soft (dolce marking!), but overall I like it much! In the sheetmusicarchive score there are 8th notes in the LH every second bar of the e flat major section, does your score did not include them? You did not play them, but that are obvious notes, I can't imagine that you would have missed them according to your score -I have to check my Henle Urtext at home for that too!
17/2: I like your phrasing of the melody on that, also in the combination with the looser rhythm! Both parts with trioles in rh (at the end and in 1st half) sound uncertain to me, the 16th notes in the middle part you play here and there almost as 8th notes, and the stretto part could come more forceful. Beside that, it is really audible that you do more on expression compared to former Mazurka takes from you!
17/3: Strange composition, but you really do something regarding expression. There are places at which you do just the opposite (compared with sheetmusicarchive score) regarding crescendo/decrescendo but I think that is absolutely ok. It is told that Chopin never played a piece twice in the same manner, and as long as it sounds musically convincing (what it does!) it can't be wrong.
17/4: Beautiful! You play it in the tone color area of the piano where it has the most capabilities to change the timbre, from mellow to bright. Don't say your Edirol would not capture that faithfully! One can hear it! Also, most of the rh runs came very well, only one was a bit fumbled, but the expression is there. Yes, it sounds way Carnevale inspired. Great!
Some comments to the other Mazurkas later.
There is never the huge contrast you hear in professional recordings.
Sorry, can't resist commenting that. If you would replace the word "recordings" with "playing" I would agree with you
Not that I feel better in that area, I know that it is a live long endeavor to explore the dynamics!
