Ey, I completely understand what you're saying. To be honest, I found your comment as a compliment for all of the artworks I've created for Roobet Art Competitions, whereas the restriction you've mentioned are for the interest of other participants who want a fair share of the top prize, that is something I don't blame.
In fact, in order to achieve of what I am today, I've spent hundreds of hours gathering information on how I can transition from traditional to digital painting. I've watched different video courses on Youtube just to know even the slightest technical detail to make a digital drawing closer to hyperrealism. And the urge to create wonderful digital drawing is a by-product of inspiration from the top digital submission during the 10th BCT Anniv. Contest.
If I can give you an advice, find your "niche" and make a habit of creating a piece on a daily basis until you become good at it. So when an opportunity comes, and Roobet announces another contest, you'd have an upperhand over everyone

It is always said that you need to spend at least 10k hours on something to be good at it, and before that there will be plenty of periods where you think you are good enough, and then feel not good enough, but after 10k hours you just become a professional at it. You are definitely a great artist, one that spent years perfecting your craft and I respect you for it. I do support the idea that you should be banned and just given a monthly stipend instead lol, you do not leave any chance for rest of us to even have a chance, you are THAT great

.
All jokes aside, kudos to you and kudos to roobet for attracting such an artist as well, we do not see people spending their talent on other casinos.
