For both submission I do have vector files. Though the second one since there's little time left, I did utilize a commercially available one with a license and added my own changes to it. Vector files can be resized without having any loss in quality.

You are disappointing me mate. Yours were my fave to win the contest. Don't come up with that excuse. Of course if you have a license you will get the vector file too from the website and you are free to edit it.
Edit: Well it's up to you abhilyall as the project owner. Sorry to see that you are wasting your time because of this issue. You could bring this issue to scam accusation which will lead them to get tagged by dt users.
Sorry mate. Should have stuck with the first submission. Well with the license, there's no plagiarism. Reason why they have subscription sites like shutterstock so we can use resources from there legally, wasn't a jpg ripped out of google or from another business. Never had any intent to plagiarise.
