Improvements:

• changed spider legs
• made the sword a little longer
• made to legs longer

Tips :

• Stick the red line from the legs to the red line at the bottom of the wither skeleton's bottom and you can change the position of the legs if you want
• Be careful not to stick the spider's legs the wrong way and you can trim the legs if you want
• you can also stick the wither skeleton to the spider and cut out the white space if you want
