hi Serpent,
Looking at the rulerships in your chart, there is a closed circuit between Mars, Moon and Mercury: your Mars is ruled by the Moon who is ruled by Mercury who is ruled by Mars (according to traditional rulerships). To emphasize this Mars-Moon-Mercury complex further, Moon is at the midpoint of the Mars-Mercury square, which is the trigger (the tightest applying square) in your chart. Both Mars and Mercury are angular (Mars on the IC, Mercury on the Dsc). Also, these two planets dispose all the planets in your chart between themselves but they are not in mutual reception: they have the Moon as a go-between.
Personally, I don't write off aspects that are wide, especially if the Sun or the Moon is involved. I also allow wider orbs for angular planets or planets that are powerful in the chart in some way (ruler of the ascendant, final dispositor, etc).
And when an aspect is separating, it does not mean that it is not powerful. And I definitely wouldn't say that a separating aspect is "easier". They are challenging in different ways. Imagine a hostage situation. The applying aspect is what leads to the event, the bank robbery, for example. The moment when the robbers show their guns and maybe start shooting around at random. People are shocked, scared, confused, etc. The separating aspect is when the hostage situation has been going on for hours or days. Let's say the bank is surrounded by the police and it's a stalemate. Nobody knows how long it will take and how it will end. I wouldn't say the latter is "easier". It's different.
As far as your hard aspects go, as I see it, you have a tight Venus-Jupiter conjunction (with Venus in her detriment), another tight Uranus-Neptune conjunction, a Uranus/Neptune-Mars opposition (with Mars in his fall), a Mercury-Mars square and a Neptune-Sun square (Sun in his fall). All your inner planets that participate in a hard aspect are either in their fall or in their detriment except Mercury.
