Hi! Im planning on entering a very large country wide art competition and the deadline is coming up soon. It costs money to enter but the prize of winning even 4th place would be allow me to go to university so choosing what pieces to submit is a LOT of pressure.

I want to submit 3 artworks (the maximum amount. My heart is set on submitting the first image attatched. Its huge (48" 36") and im really proud of it. The 2nd image I attached (22" 22") is what im considering the most out of my options as my second submission though I havent decided on it 100% The rest of the images are potentials for the third.

The main prize is judged by a panel and the other 3 are a people's choice so theyre voted on. The website states that the panel judges based on originality, quality of artistic composition & design, creativity in expression, and overall presentation. There is no theme so its completely open.

For the 3rd image (portrait) im really proud of it but im worried its too dark to stand out and its very small

My mom is insisting on the 4th and 5th images. The 4th is bright which is good but I got a lot of critiques on it because its quite messy and everything blends together too much. As for the sculpture I just personally hate it a lot its kinda poorly sculpted and I feel it may be kinda unoriginal. If I do choose to submit the sculpture I will finish the paint job on it with a lot more colour variation and a blotchy brush stroke heavy look. The only reason I'm considering it is because it might stand out
