Yay for me!, I worked it out in the end all by self!!

I'd say, take off the background.
What you got from cutting pic from below you lost with the background. It is quite narrow and long picture - bit of a trouble. I'd recommend to use it on that size as it is in the picture now, just without the bg. Just be careful that you don't mess the original dimensions, shoes and buttocks of the dragon are well drawn, they ought to be shown.
