T-shirt mockup featuring a young woman

Create a realistic T-shirt mockup featuring a young, sweet woman with brown, curly hair. She is smiling beautifully and holding her hands open with the palms facing upward, as if she is overwhelmed with joy and excitement. In the background, there is an incredible natural landscape viewed from a large mountain, showcasing stunning scenery and lush greenery. She is wearing a white T-shirt, providing plenty of space on the shirt to display your design. The scene should be bright and vibrant, capturing a sense of happiness, wonder, and connection with nature. Ensure the lighting is natural, highlighting her joyful expression and the scenic background, with the T-shirt clearly in focus for your design placement.
