Always nice to hear ya! I'm typing the first paragraph here after my first listen (usually more reflective of my subjective first impressions) and the second after I've listened to it 4 times.
You have a solid hook here which is definitely characteristic of your house music inspired style. I effing love how the style changed at 2:13 to a synthwave-ish kinda style (mostly just cause I've been listening to Carpenter Brut recently). Some synthwave music uses a rhythm which includes a bass arp like the one you have in your first drop. I think something like that would have fit there with the same kind of manual sidechaining you have on the first one maybe with some minor bitcrushing.

Now I've listened to this a couple times. The piano stands out to me, I think because I come from a family where everyone plays piano and so expression in velocity is something that is just kind of important to me (house doesn't typically give a fuck about the next point I'm making). When a pianist plays, every key is hit with a different velocity but also some keys (even within the same chord) are plays with different velocities intentionally as to add more expression. This is where having a velocity-sensitive keyboard really comes into play as it becomes much easier to capture the expression from your keystrokes (may require some piano experience). Just a technique I think you could incorporate for now is just playing with the velocities of all the notes until you find something which seems for expressive to you (a lot of inspiration for velocity expression in piano comes from classical music in my case, it may take some listening to get a feel for it). I do think it can be applied to house though. Maybe playing with some more reverb on the piano would be nice too (I just like reverbed pianos, I may be biased there)
Still love the synthwave-ish part, you're definitely getting better at using portamento in your hooks now, which is definitely something that can be risky if you don't know what you're doing. It works very well here. I like the tom fills you have and how you used them to transition. Maybe one thing I would say is try giving your leads some breathing room, like whether it's giving the center-stage to a percussive sound for a beat or two or maybe a riff of another instrument can come through for a moment, even making room for some silence would be good. I think the next step for you on a technical level is stereo effects and 'placing' instruments in a way that can create a space. This definitely stresses the use of reverbs as well.
Alright, there are all my jumbled thoughts on this, good work my dude! Look forward to hearing more!
