I don't like to argue, but is the style you call yours drawing someone elses characters and posting them online without even giving credit? You should think it through again bud. Not saying you can't draw someone elses drawings for fun, but you shouldn't post them online without giving credit, and entering a competition with it is even more of a nono.
The letters are probably his, but the characters are definetly from a youtuber called Vexx. Here's vexxes instagram: https://www.instagram.com/vexx/?hl=fi
I know right, just like I said before, draw other peoples things for fun but don't enter competitions with them... peace
