Yes, and watch the edges on the heart models, the guy has white showing on his head from the original, (virtually guaranteed to get binned with that).
When doing edges, use the pen tool, then press SHIFT, CONTROL, I and then DELETE to get rid of the background, and then the same again and use the stamp tool to push the edges up so it looks clean.
And watch the white on the edges DELETE may not remove it all.
Good luck.
But as NIco said, also put in a lot more effort, doing these at high speeds comes later.
Regards.
