I hope you’re enjoying art fundamentals. I looked up your art and to me, it looks like you have the skills to get in so as long as you finish and you’re satisfied with your porftolio, I wouldn’t worry. I’m not very good at giving people advices but I’ll just tell you the things I did to get better.
I used to draw a lot of anime and realistic style so it took some time to shift to more of a cartoony style. So I started looking at artists online who had a cartoony style that i liked and observed how they draw. I studied how they do shapes and analyzed what I liked about their art. This way I have a visual memory of their art. So when it comes to the time that I have to do my own, I will implement some of those things that I learned.
I did a lot of caricatures of people. everyday people. Observing them. How they move, talk, etc.. Think of how you can portray their personality and character into your drawing.
Draw a lot. Draw every time you get the chance to. Be playful with your drawings. playful with your shapes. play with different proportions. Do different silhouettes for the same character and see how many you can come up with. Try to slowly move away from having the proportions of the body right all the time. And most of all, have fun.
Looking at art books also helped. Check out some of these books that I find were helpful when I was working on my character:
Creating Characters with Personality by Tom Bancroft
Action Cartooning, and Fantasy Cartooning by Ben Caldwell
Any of Stephen Silvers and David Colman’s books
One more thing, When you’re doing your character for portfolio, try to keep it simple. Only add designs that are necessary to your character.
I hope this helps. I tried to keep it short. I wish you luck on your portfolio and hope to see you in the studios next year!
