Hi Andre,
That's not bad.
I assume you shot several, perhaps in burst mode - and selected the best compromise for subject focus and web sharpness?
(If not, there's a suggestion)
I couldn't see any useful EXIF data which revealed what aperture you used, obviously a narrower one will give more Depth of Field; e.g. f/11 or f/16.
Have a look at my four attempts
in this gallery, it may give you some ideas.
Probably the best idea is to try to find, perhaps another spider, which you can shoot from 'above', like a couple of mine are, but you'll note my first attempt was also from below (and I think yours is better).
Good luck, plenty around at this time of year (well here in UK anyway) - at least until the frosts start.
Cheers, Dave
