I think the shape of the card is unique and overall the design fits the brief well. I would be cautious about using gold text on a pink background as it may not provide enough contrast to be accessible, and I would also avoid using shadow effects on text for the same reason + it can make issues with legibility. Overall the idea is really good just could use a couple minor tweaks :)
I love the shape of the business cards as it perfectly brings in the cloud element the brief was looking for. The only thing I'd note is to reduce the spacing on the script font you used for the "Jennifer's Heaven" part.
Hey Darebe! try learning Illustrator and photoshop as a beginner, but let me tell you knowing software is not the most important; study design as a discipline, learn design elements like composition, forms, color, positioning.
This way no matter what software you use, you will have the ability to create beautiful functional designs.
