Firstly, the middle of the flower (not gettin' the name atm) is crappy. It needs some detailing. The petals aren't looking natural enough. The shading isn't proper. The stalk, or stem, for that matter, is quite uneven. It doesn't look good. The leaves aren't totally proper either. And..
..that's enough for a day, I guess? xD;
Well, I still can't see the pic. ;;
