>>65350136/10 - Not really a fan of that wallpaper, I think either something with grey, or darker colours would look a lot better with those icons. I think it'd also look better if you moved all the icons down one space, and put the groove icon above the others rather than below.
>>65351599/10 - Issues I have with this are incredibly subjective, but I like cleaner, simpler looking fonts like Helvetica, and I focus a lot more in practicality, and that 'new phone, who dis?' thing doesn't look like it serves much of a purpose at first glance. Otherwise, it's very well put together.
>>65352107/10 - Generally not a fan of those sorts of fonts, as I stated previously, but I think it works here. Main thing I don't like is the calendar widget above the clock. The days are a bit too close together, and the date looks a bit awkward where it is. I think it'd be best to have a widget that displays the full date (i.e. Thu April 7, or something along those lines) and not the other days. Otherwise, its quite good.
>>65352697/10 - Not a fan of that font, I really think something light and clean would work better. A slight blur effect on some of the widget backgrounds (particularly the clock, system stats, and what I assume is the battery) would keep the focus on the content of the widgets while still retaining the aesthetic you're going for.
