amazing learning experience .
Great course! I especially loved (and appreciated) all the very specific information about what you should include in your portfolio (that I have not heard before) - lots of different expressions, adults AND children, spot illustrations along with detailed background illustrations, etc.
really great tips for starting my journey in children's books illustration-- thank you!
One of the most complete portfolio courses I've ever seen! Super insightful and detailed, even when I studied illustration I didn't have such a complete explanation on how to manage and make a proper portfolio as I did here. I feel so grateful to Marissa for sharing with us so many professional advises🌟
Excelente curso !!
