Pisces rising tends to make for friendly, but shyer and a bit more withdrawn than most Leos usually would seem up front. Also, with Pisces rising, your 7th house cusp is in Virgo. Counting backwards, your 6th house is in Leo, which is also where your sun falls. So even though you're a Leo, you are going to be drawn to Virgoan-type interests in your life - health, fitness/being fit, artistic pursuits that require precision or fine detail, teaching, life as art (virgo rules work and daily mundane rituals that are needed to maintain one's self - thing getting up, showering, brushing one's teeth, eating on a schedule, etc)

Moon in Scorpio also makes for a bit more withdrawn Leo, but this more in the secretive realm. Slow to trust and open up, but also slow to let go. Especially mixed with your sun, this is a powerful moon for going for what you want and getting it, though sometimes when it's a person, it's best that they are on the same page as you about that or you could waste a lot of misdirected energy obsessing when you could move on.

Mercury in Virgo means you communicate like a Virgo. It also means you always want to know why? how? when? where? what? And not just any old information. Useful, applicable, practical information. You may still know a little about a lot, but usually there are a few topics that are special to you that you have taken the time to learn or study in depth. Most likely your Mercury is in the 7th house, so your thought process leans towards how to create relationships, how to maintain harmony, and/or how to work out conflicts.
