Only vectors will cut. The SVG file type can hold vectors and rasters, so if you used a jpg (raster) clipart image, and just saved it as an SVG without converting it first, you don’t have a vector. At 11mb, I can only assume that the SVG had raster data in it. The file looks like 12kb when I vectorize it.
I don’t know your experience level with all of this, so I would suggest looking through the matrix of design tutorials here: Community Glowforge Tutorials: Table of Contents
here is the vector I auto-traced from the JPG you posted: I would probably alter or delete the scrollwork in the base if it is going to be cut small, or make it an engrave. very close cutlines.
