Hey can anyone help? I am trying to create an SVG for my daughter - I drew it out and when I export it as an SVG / PNG or Jpeg half the lines look correct and half look wrong attaching the photo to see if anyone can tell what I did OY
The first two are how they look in affinity - the third picture is after I have exported it and try to make it on my cricut 
 
any thoughts or ideas whatI am doing wrong?

MattP THANK YOU!
OK so - I am clueless for sure and totally appreciate the help - did you fix my svg?  If so AMAZING - still clueless as to what I did different. I did use the vector brush tool for the first part ( thought I did with the second) (Are you able to tell what I used for the second side if it wasn't the Vector Brush Tool?) 
I thought I used the vector brush for the whole thing - obviously not -  I am not sure what the heck I did LOL - I haven't learned how to remove parts of the picture by cutting them yet - I did just get my book and am taking a lesson on UDEMY - but to be truthful I am a hands on person and having trouble grasping things - probably my age LOL.  This forum is awesome  and again I appreciate your help (even if I am clueless)
