There have been several threads on flower shots recently and having commented on other folks, thought maybe I should put up some of mine for you to pull apart
1 - spring (or summer) snowflake, something with no business on the windy ridge at the top of our garden as it is a river-side plant (and must have overheard, not showed this year). This shows the difficulty of getting DOF right through on even a 10x10x10mm specimen, but I hope just enoughish
2 - Camelia Japonica or Quince
again a bit short of DOF, but I hope getting the 3D form and colour pretty good despite and away from stereotype single bloom in isolation from background
