Seriously, I give you two thumbs up just for working with a Canon AE-1... wow! That's a mid-seventies SLR... literally the first mass-produced SLR with a microprocessor. I recently had one of those come through my pawn shop and couldn't help but learn a thing or two about it before it sold. I'm out a couple times a week with my Nikon DSLR... but I could never imagine using the AE-1... it was kind of a fun antique for me to look at. More power to ya, though, keep at it!
If could make one major suggestion, it would be to try limiting your flower/plant photography to overcast days. The shadows cast within the flowers distracts from their inherent intricacy. Avoid shooting mid-day, especially on really clear days when the Sun produces an overwhelming source of unidirectional light. These flower shots would be much better overall photographs with the help of more diffuse natural lighting that would limit, if not eliminate, patterns of shadow. Luckily, cloud cover is your best friend for achieving such conditions.
