Beading Software

I'm debating whether to get a beading soft ware or not. For now I have a trial version of Bead tool 3.0 and it is free. I cannot get the pattern in Delica color codes from the trial version but I can transfer images. However I'm not totally happy with the transfers. Images containing few colors and very simple like this Lotus below works fine.
but more complex images like photos doesn't work as well



These are the original images.
