GQLMAO's Small Peninsula Tank

[gqlmao]

Some macro shots, I am a total beginner at it. It's a T5i with EF 100mm 2.8 macro lense. If you guys got tips throw them at me. So far I am finding a very small aperture (32f), longer shutter speed (1 sec), iso 400, no flash to give me useable pictures. If you got some advice I would appreciate it!
