First off,...nice Micrurus f. fulvius!
Well, there are many different ways to get decent macro shot's, and they all depend on many different factors. But they usually come out pretty good on most cameras in the "auto" setting if you have a good above light source(i.e. natural sun light) or other strong lamp source from above, and even from the sides as well to eliminate shadows, and to fully illuminate the subject.
Many times incandescent, florescent bulbs, etc... can make the photo turn out somewhat yellow, and/or dark, and on many cameras there are settings to comensate for those conditions. Another way to get a fair closeup photo without actually getting super close, is to set the camera on a large pixel format, then crop it down in your photo program for that camera, or a number of other programs even. Then when you crop the huge formatted pic, it is reduced down to a much more manageable size, and in the process "blows up" the subject intended.
Also, on most programs, you can lighten or darken pics to better compensate for poor lighting conditions, or even ones that were too bright as well.
Check out your instruction manual real well, and you might get some good "pointers" to use for that particular camera. I will say though, that many times taking GOOD photos can take a lot of trial and error!..LOL!, this I know from botching a bunch myself!
One other way to get fairly good pics inside with a flash, is to do as I mentioned earlier with a big pic format setting put a folded paper towel in front of the flash, and it tends to not "wash-out" the pic as much, and the paper towel, or tissue acts as a "flash suppressor" of sorts. Another suggestion is don't take pics with strong light in the background(backlighting), this will certainly make the subject way too dark.
In any case, it can be really frustrating at times, so don't feel alone..LOL! Experiment with some of these things, and you'll likely develop a sense of what works well for you in certain conditions.
Good luck bro!
