To jump or not to jump

This is a litte juvenile Marpissa muscosa I think.

Nice, Pablo. Almost razor thin DOF though. What was the F stop?

The F stop is 10. The DOF should have been larger. The thing is, this was shot with the build in flash and when I wanna shoot with F 16 the picture is much too dark, and a high iso ain't gonna work out perfectly if I want a good sharpness (even more visible when cropping)..So...I want a good flash with diffuser next summer .. Or, are there any other tips?
